THANK YOU. Your video is much better and more straight forward than the service manual and your suggestion of using the bolt to affix the vacuum rubber worked perfectly (perhaps 'almost' perfectly, time will tell). I layered multiple nuts on it to achieve the right length, there's room for it. I no longer have that annoying HISSING in the dash. This has been one of the final fixes on my never-ending-rabbit-hole-list. MAN, when the car starts really coming together again it is something to behold.... an addictive achievement. There is a Zen in it all.
Great info thanks! Do you know if the grey wire on the right side of the control unit is the radiator fan control signal? When I turn on the AC the radiator fan is supposed to turn on but does not. It does turn on when the engine heats up.
Great video, great information and good camera angles. But mine still not working, I replaced the carpeting in my car, could I have blocked the damper or something?
Question not related to the HVAC fix…I have a 1992 Trans Am 305L. New to the auto world and wondering why your engine looks so much different than mine? Mine has the air filter pan on top. I like the clean look of yours. May be a stupid question but was curious.
Great video! My car came without factory setup due to an engine swap from the previous owner so i dnt have a lot of the vacuum valves under the hood. I did the fix you did but still goes straight to defrost. I have no clue of what else to do. Any input?
hey man quick question, that vacuum hose at 3:43, is that neccesary to make everything work correctly? I recently bought a 3rd gen that I had to replace the hvac valve and it never came with that hose connector on top. Also, what might that hose connect to lol? Thanks dude-
hey man not too sure how ur doin since this post but i’m having the same issue atm. That emissions tube on the heater control valve snapped in half on my maro and i need to replace it for a new one but my only problem is i lose sight of the tubing after the firewall and don’t know where it leads to. Please let me know if you’ve had any luck with it:)
If i had the broken piece I would solder it back on or if I no longer had it I would pick up some wire and re create the loop and solder the piece onto the main cable
Help!! I have a problem with my 3rd gen camaro, when the car is running I get air through my vents and the knob that controls my air speed isn't working inside it won't do anything. I don't know what to do
1992 Pontiac Firebird - Blower Motor Switch -- I took out my radio out and put my finger on the back side and wiggled it -- on MAX - the MED-HI fan was engaged ...and the LOW worked .. but not HIGH or MED-LO ... I think it is this part... Standard Motor Product Part Number: 4659-06095888: HVAC Blower Motor Switch. UPDATE: There are 5 Copper prongs on this switch. There was one that got HOT and melted the plastic around it. I would say this is the problem. The OEM Part Number is 16068778. The metal hanger I think can be used again - but there are 3 little clamps that hold it in there. The NEW part is different in the screw placement on the gold metal setup is straight up & down. Mine OEM part has them opposite ends.
It is suppose to be hard, the wire attached to the vent door is very short and the vacuum lines are short too. You just have to try and pull them up carefully or disconnect some

Haven’t had heat other than in defrost mode for years. Fixed! Thanks for a great video.
Appreciate you showing the flap doors and cable end even though that wasn't your issue. Very thorough video.
Your intro mute b th loudest on RUclips geesh lol but I subbed. Just bought an 88 rs and I needed everything u said about th camaro, thanx...
Have fixed the loud intro since then.
Got a 87 iroc z28 today and seller was selling for cheap cause ac didn’t work, this helped me fix it. Thank you very much.

Do you have heat or the vent working? Or is yours stuck on the defrost?

You have throttle body injection, TBI for short. His car is equipped with tuned port injection or TPI. just different fuel injection options.
Hey man my little flappy flap broke off the plastic it was mounted to when I was replacing the heater core, what do I do and what does it do ?
Great video! My car came without factory setup due to an engine swap from the previous owner so i dnt have a lot of the vacuum valves under the hood. I did the fix you did but still goes straight to defrost. I have no clue of what else to do. Any input?
Seeing as the switch leaks vacuum, would this affect the engine?

Hey what size screw did you use?
What kind of t “vacuum connection is that” I just find some regular t connections
Anyone know what the metal piece is called that actuates the flapper and connects to the cable
Yeah that’s exactly what I’m trying figure because In the video the little wire piece that circles around the cold and hot air because my is broke
Your my hero 💪🏻💪🏻💪🏻
Hey man i have a question how would you go about fixing the blend door cable if it broke off ?
If i had the broken piece I would solder it back on or if I no longer had it I would pick up some wire and re create the loop and solder the piece onto the main cable
J Robling Thanks so much but my whole piece turned into crumbs lol im not sure what to do at this point 😞
Help!! I have a problem with my 3rd gen camaro, when the car is running I get air through my vents and the knob that controls my air speed isn't working inside it won't do anything. I don't know what to do
Take it apart like it did in the video and find out what isn't working. Trace the lines that control the speed
Same problem on my 91 rs thank you
Thanks so much man I been trying to figure out what was wrong with mine
What would happen if your control works but it squals when you start up and goes away after 5 minutes?
Sounds like the fan bearings need to be re greased
Thanks man I got mine fixed
what if the leak is in the left side vacuum hoses. how do you repair that?
Find the leak and repair the hose. I had to do that with one of the vacuum lines for my cruise control, just used some electrical tape for the hole

I AM TRYING TO DO THIS TO MINE BUT WHEN I TRY TO PULL OUT THE UNIT ITS VERY TIGHT LIKE I AM PULLING WAY TO HARD. HELP!!!
It is suppose to be hard, the wire attached to the vent door is very short and the vacuum lines are short too. You just have to try and pull them up carefully or disconnect some
What is the grey actuator at 1:54 anyone have a link?
I also have the same issue, mine broke into pieces. I'm not sure if replacements exist, I am going to try to make a new one myself.
