whats up guys? So i have a problem with my a/c. Its been acting funny lately. last summer the ac worked great! super cold all the time. This summer comes around and it blows hot air. Had the freon vacuumed and recharged and the ac still does not blow cold unless i rev my engine up really high and hold it there. If i am driving normal or not reving the motor the ac will not blow cold air. Any ideas???
Thanks in advance

try changing your cabin filter its real cheap bout 14 bucks or so my friend did that and his ac was blowing super cold!!!

to locate it you pop ur hood and the black plastic part that sits underneath or i should say right where your windshield wipers are comes off its got lil screws that pop up be careful use a 10mm socket to push them up you should find ur filter there sorry dont member what side its on if its real dirty try changing it maybe it will help...and sorry in advance for sucky instructions lol

 

Cabin filter isn't going to effect vent temp. It's most likely low on refrigerant. Take it back to the shop that serviced it before.

 

you might have a leak or your compresor went bad

 

does anyone know what psi the freon is supposed to be at?

 

i think it says it in the engine bay under the hood where the radiator is. im not sure tho

 

There is a high and a low side to an A/C unit, so 2 different PSI numbers.

You may have proper PSI but a blown A/C clutch or slipping belt.
