I’m currently experiencing the same thing as your original issue. I’ll have to double check wires. I have replaced hi/low pressure sensor, a/c relay, Freon good, fuses good. If I bypass at the relay clutch works fine and it’s ice cold inside. My step dad said it was the clutch but now I know it’s not. I’ll be checking wire tmrw. I just hope it’s not a wire near impossible to get to. Thanks for vid it gives me one more possible solution. I’ll get the multimeter out tmrw!
Thank you for the video sir you just saved my life yeah that Texas summer heat is not a joke but your video helped me out had my compressor wire disconnected soon as I plugged it in compressor came on 👌
Pon un video mi compa pa saver como lo arreglaste porque aquí en oklahoma el calor también está fuerte y yo tengo ese mismo problema pa saver cual abre es
LOL the way you hit the hood to get it to open. Classic GM. Also there’s little rubber bumpers that screw in and out by hand, that push the hood up when you pull the hood release inside the truck.
@@JB-cw5uumine did the same thing all I did was dump oil on the latch and the coil things for the hood get her all lubricated and now it opens like a dream
Nice truck I've got s 98 silverado I would suggest a catch can on the drivers side to keep blow by and vapor out of your cylinders I I have a 3 ounce Jtl brand and I get about an ounce every 3k it also keeps the spider assembly cleaner keep up the good work on your ride
Ya I’ve had it since I was 19 I bought it with about 17k on it. Drive it for almost 340k before I finally rebuilt the motor . When i did we built it up to about 400 hp at the wheels lots of goodies in it. Put a 6” lift on it and 20” wheels and 37” tires 4:56 gears new paint,pretty well done everything except the interior . It could use a facelift inside. Needs a new dash board, front seats and carpet. I’ll sell it if the price is right. It sits under my shed most of the time
Good deal. Sounds like it has plenty HP. Headers make it sound pure and not generic. I wish mine had them. I have a 98 also and everything is original. I’ve had it since 2001 from my Dad and it only had 22,000. Now has 180.000. Lots of people want to buy it but I’ll never sell it because of sentimental reasons .
I got a question sir, I'm having the same problem. When the compressor would work for you, did you ac light work on the control panel and also, when you ran the green wire to your battery, could you still turn the AC on and off with the switch inside. Thank you for any help, I'm not a mechanic either so trying to fix my problem on my own to.
When it was broken I was able to make the compressor run but jumping a wire from the compressor,directly to the battery , I’m not sure if the lights inside came on or not, I don’t remember. all that did was bypass all the interior switches and deliver the power from the battery to the compressor directly, when doing that none of the switches inside the truck will make a difference because it’s getting its input straight from battery to compressor.I ran it like this for awhile by routing a wire from the compressor to inside my truck with an simple on/off toggle switch then from switch to battery , this enabled me to manually turn the compressor on and off ,totally bypassing the trucks relays and switches , it worked but was inconvenient because doing that you will have to periodically turn the switch on and off to manually kick the compressor on and off , it’s not supposed to run 100%of the time, the relays job is to open and close the circuit as needed but since all that was bypassed I had to do it manually , if left on it would freeze up and possibly drain the battery or burn the jumper wire, but it did work in a pinch until I found that broken wire as noted in the video
thanks. I’ve had it since. 98 I was 19 when I got it. finally got where I was able to make it like I wanted 25 yrs later. been a great truck stock engine was still running when we rebuilt it at 330k
Would this be the same if the ac compressor is turning then stopping it was blowing cold then stop blowing cold still works just not cold but like I said it will turn then stop and keep doing that
sorry I don’t I had my mechanic friend pick them up at a local speed shop in Tyler Texas , I had a hard time finding them too because i needed the added clearance and the tall center bolt covers were tricky to find
quick response I’ll make a vid later . 383 stroker kit new injectors stock size with high flow fuel pump comp cam extreme energy high torque remember for sure but I wanna say it’s a round 280 intake and 290 exhaust. 1.6 roller rockers with guide plates , bored .040 , 10:1compression I wanted to run pump gas long tube headers, reprogrammed computer, I built it to pull really strong and it does. when I had at dyno test it pulled really hard and measured 320 hp at the wheels but kept stalling at 4500 rpm, that’s when we discovered it was starving for fuel I didnt wanna spend another $500 to have it tested again but we estimate it’s pulling around 400 hp at the wheels if I didn’t have the lift and big tires on it I’d like to see what it tops out at but I’m afraid I’m gonna kill myself in it if I try that now , when it gets up in the 90s and 100 mph range I have a gear left and more pedal and it’s hard to keep on the road when I had 32” tires on it it would not hookup from a hard start very good just smoke the tires , went to 37” tires and it grabs hard now running 4:56 gears mpg is terrible 8-10
The paperclip is used to touch the two terminals together. Connecting the circuit. Basically taking the place of the switch to see if it’s a switch problem
Yes if Freon is really low it would do that , I’m sure there’s probably other reason it would as well but mine did that one time when from had leaked out and it was critically low
@@JB-cw5uu right, I’ve done Freon, leaks, condenser, compressor and clutch, control panel, relay and still won’t stop engaging on and off. Even if control panel off or heater on.
@@JB-cw5uu well I have same issue exactly the same Siri need to change that wire the green one from low pressure switch when I try to jump the connector does turn the clutch on exactly like your vide so u followed the green wire from switch all the way to where u changed that wire out I know that’s my problem just like yours
Nice truck dude good job on it. I've got a 94 Siverado, I'm the original owner it has the original engine and transmission just add the transmission rebuilt it was sloppy and I'm about to turn 500000 the original engine is untouched
Yes sir. I believe it. This one here ran over 340k before I rebuilt it and it was still running daily. That was after working it for 20 years hard in my roofing business. Pulling trailers and all over town doing estimates daily. Very good trucks
God bless you sir. I checked my voltage from the pressure sensor and found that the wire was broken. Fixed it and now my A/c blows cold 🥶
Awesome glad it worked
Doing mine today... thanks. I joke that you never see a 98 GMC with it's windows up on a 100 degree day. Northern California.
Thanks to your video I tracked down the burnt wires. My black wire was broke in half! Got the compressor going again thanks to your help!!!
God bless you! Thank you for this advice. Literally found my problem seconds after watching your video.
Awesome glad to be a help
Man that’s a beautiful truck 🙌🏽
Thanks .. wanna buy it ? Make me an offer. It sits under my carport 90% of the time
Thankyou! So much dude! Youve given me a few things to look over i have pressure no leaks i cant figure it out

Hey Mike Hosler did you find out what the problem was I have the same problem.
appreciate it man, going to try this in the morning. Hopefully it does the trick. Having the same problems you were having.

Ya this one has been like that for years. I’ve gotten so used to it I bump it and don’t even think about it

It’s a little on the loud side lol has short packs on it with headers and true duals

you know what cam u got i wanna build my motor and have plenty of torque
Thank you for taking time to make this!! Huge help!
Your welcome. I know I searched all over with no luck. So I was hoping others would benefit from the post. Glad it helped
Hey I was wondering on them valve covers I have a vortec and put some afr heads and having some rocker clearance do you have a parts number on them
sorry I don’t I had my mechanic friend pick them up at a local speed shop in Tyler Texas , I had a hard time finding them too because i needed the added clearance and the tall center bolt covers were tricky to find
Thank you so much
Yw.
can you make a video what was done to the motor and MPG?

The paper clip u insert with the truck on or can u explain a bit to me a bit more thanks
The paperclip is used to touch the two terminals together. Connecting the circuit. Basically taking the place of the switch to see if it’s a switch problem
Would the fan still run? I turn mine on and it does nothing. Ive changed the fan motor and resistor. Still nothing.
Mine would run but the compressor would not kick in. Till I fixed that wire
Did you ever experience ac clutch engaging on and off continuously?
Yes if Freon is really low it would do that , I’m sure there’s probably other reason it would as well but mine did that one time when from had leaked out and it was critically low
@@JB-cw5uu right, I’ve done Freon, leaks, condenser, compressor and clutch, control panel, relay and still won’t stop engaging on and off. Even if control panel off or heater on.
@@josuesalazar3603hmm In not sure I’m not a mechanic but may possibly be the low pressure switch ?? Just guessing I’m really not sure
@@JB-cw5uu yeah i thought too unfortunately didn’t do it. Thanks for your help
@@josuesalazar3603did you ever figure it out. I have the same issue
Where’d you get that grille
The guy that painted it for me got it. I’m not sure where though . I ordered the headlights online I think from eBay
Do you know where to buy a brand new dashboard? I have a 98 c1500
You can buy one at junkyards. Sometimes they’re good and cheap.
Ebay
Man is talking about everything but the doggone compressor 🤦🏽♂️
Compressors is fine. It’s the wiring
Someone tell me in Spanish what was that he said because that is the problem I have
Hey mr John I have exactly same issue dealer could figure it out if I drive to u could u help me out I’m in Lewisville tx u have a number
I sorry I’m not a pro just work on my own stuff now and then.. wish I knew a bit more to help you out
@@JB-cw5uu well I have same issue exactly the same Siri need to change that wire the green one from low pressure switch when I try to jump the connector does turn the clutch on exactly like your vide so u followed the green wire from switch all the way to where u changed that wire out I know that’s my problem just like yours
The back of that intake over years of heat apparently will eventually damage the wires behind it. At least that’s my assumption.
Nice truck dude good job on it.
