A/C BLOWS HOT AIR WHEN VEHICLE IS NOT MOVING BUT A/C BLOWS COLD AIR WHEN DRIVING

- In this video I explain why the A/C blows hot air at idle, at the stop light or when not moving and why it blows cold air when driving.

Also check that the small condenser fan under the hood is blowing when you start your vehicle. The fan blades could just be stuck. If the fan isn’t blowing, take a screwdriver and tap the blades to see if they just needed to be freed up. Watch your fingers.
Change your cabin air filter , regularly .
Excellent video! Thank you
Thanks for the good video
Thanks for sharing
Thank You 😊
Thanks for the valuable information.
What about the compressor if it bad? Will not have similar symptoms?
Yes
And I see on here people questioning about the compressor clutch engaging on any car they also incorporate an AC compressor control valve in a lot of these cars that the compressor is engaged one hundred percent of the time even if your AC is off and that is the purpose of that valve in the compressor the symptoms would be that your gauge readings are almost correct but at idle the air gets a lot warmer that's usually a cooling fan problem or an AC compressor control valve only not the compressor itself
Hey, I have a g35 with a p0024 and it gets 9 mpg which is terrible milege, I took it to the dealership and they said it could be magnetic retarders or faulty timing chain.(I watched your video on timing chain and I have no bad symptoms and my car idols, starts and accelerates very nicely.)Can you please tell me what the problem could be. I would really apreciate it
Start by checking the timing chain. Issue could be caused by stretched timing chain, worn guides, weak tensioner etc...check connection and broken wires at the camshaft position sensor as well.
WOW! THANKS!
Very interesting and helpful information. A faulty ac condenser fan can also contribute to this ? Thanks
Yes it can.
@@Top5AutoRepairs Thank you
My 03 is doing the same thing but estimating its charged based off the ounces in the cans we use after vacuum the system. Also notice my compressor never cycles off. Any ideas or suggestions?
The ac clutch is probably welded stuck
@@zackgambrell5391 new compressor
I have the same Honda and I recharge it, but that's not helping. I'll have to take it to the shop
Too mymuch Freon give same effects
Not for a Honda. It could be that one electric fan at the backside of the radiator is not working. FYI
My car has the save issue but when i hooked up the Freon the needle jumped all the way passed the red zone. Help😊
Means you need to bleed the pressure off. Hold the pin inside the thing down, it'll bubble green stuff. Hold it down until the pressure is in the range you need it to be and it should start cooling. Your ac system is OVER charged.
I was told that car freeon only gets cold wen there is a leak on the system otherwise would never runn low nor had to be recharged. Is that true?
Yes if you have a leak, then it will need to be fix or replaced, if it was good forever, it would never have to be replaced
Man i have this problem and I think I'm gonna change my condenser i changed my compressor and still has the problem but it's 70% efficient😢 😢
You know I see different vehicles with different AC symptoms and I see a lot of questions on here with people trying to fix their own air conditioning if you guys are not mechanically inclined and you do not know how an AC system work you could be actually causing more problems for yourself
It's impossible to see exactly what a AC system is doing when you don't use a regular set of AC gauges for the low side and also the high side. I guess these little blue low side hoses and refrigerant cans sell good. I've used the cans myself but I use a regular set of gauges.
I've had so called professionals look at my ac and no one has figured it out yet
Oh this is funny how I looked this up and it's the same exact car that I'm having issues
Would you recommend taking a vehicle to a shop for full on AC service? No idea when my 98 civic was last serviced. Didn't know that iconic Honda tick was in J series as well lmao
Yes the infamous tick
My ac goes back and forth hot cold hot cold. My temperature gage gets hot to mid hot back to mid. What causes that
My shit does exactly the same
@@dantheman8471it could be your thermostat but I would change the Freon first
mine does this as well but then it also overheats at idle and then temperature goes back to normal when driving. What could that be? I have no codes or a check engine light on.
Sounds like not enough air flow. Depending on your vehicle you might either a bad fan clutch or your electric fans might not be kicking on
My car does the opposite any advice😅 but i being serious 😁
I'm jealous 😆 🤣
I did this. Filled in the green just as instructed. My car still blows hot when stopped but cool when driving. I can hear the compressor turning on and off quite a bit while stopped. Is it possible that air somehow got in the line and that is messing up the pressure?
Did you fix it? Mine is same
It blows cold when moving but a bit warm idling
@@africanlifeempire8108 No. Pressures are all over the place. I was told by the mechanic that the compression is going bad. This is why it can be puzzling when you watch RUclips auto repair videos because the condition of each particular a/c system is different. I had so many RUclips "armchair" mechanics say, "It's this" or "It's that" when it was actually the other thing.
Low on freon does not remedy every ac problem. My car was blowing warm air at idle. Going down the road it would do great.
THE FIX,,,CLEANED THE THROTTLE BODY.
Hello, I drive a Honda 2003 accord UK model, I've been going through hell with my car ac, changed compressor thrice and jst before it dies, It gives a sign of hot air at idle and only blows cold when my rpm was above 1000 rpm n gradually up to 2000rpm and now blows hot at all rpm. Am frustrated with spending money on short time fix with in the hands of some moron in a workshop suit claims to be an ac expert. Please, how did u fix yours and what was the failing signs, also what car do u drive. Thanks, hope to hear from you.
@@desmondlouis5762hi any update to your ac now?
@@JMVenturesTV still no good yet. D last time I changed condenser, compressor, freezer, expansion valve but couldn't find d the exact ac line that matches my cars own, so I cleaned my old 1, which was a terrible mistake. After 2 days the ac stopped blowing cold and I stopped using d ac, checked the refrigerant level n noticed silver colored fragments in refrigerant.
What if it has freon on it but still only gets real cold when driving?
Check the compressor belt. It might be loose
What causes AC pressure switch to prematurely fail in a week even though it is original and not replacement?
OEM stuff fails. I had some wheel bearings go on me way too soon. A professional mechanic friend told me that I was paranoid. Well he had a big glass of STFU when it was in fact the wheel bearings. A nurse once laughed at me when I thought I had colon cancer. It turned out to be Stage IIIB colon cancer and I almost died.
@@yishihara55527dawg how did you know
@@nickdashtick5467 Distinct sound like a helicopter.
@@yishihara55527 nah about the cancer
@@nickdashtick5467 They found out after they did a colon resection. Lab results said it was stage IIIB.
FREON is a brand, people stop calling Refrigerant FREON....thats like calling paper towels SCOTT TOWELS or Baking soda ARMNHAMMER
Who cares?
@@rvilla4257 Who cares that you don't care...
😂 pass me some Kleenex. Sorry I don’t have Kleenex, only Facial Tissue.
@@tommyvang17 you're catching on
No one cares
