Question type: Maintenance & Repair

My car is not blowing cold air out of the vents. put the gauge on to check the psi and it was up in the red. what should I do

3 Answers


if the cooling system is in the red you need to find out why, no cooling fans, plugged radiator, bad thermostat, etc, if the heat control knob is turned off then it will only blow in outside air and if that air is warm so will the air out the vents. Now if you had A/C and it was working properly and turned on the air would be cool.

Sounds like the system is overcharged or some other issue. A/C repairs need to be done by a professional.


Great advice. you can add it to anything... Blah blah blah, needs to be done by a professional. I'm sure many things can be done on the ac units without having to be a "pro." IE, replacing bad switches, usually charging system.. etc. It's a little fluid dynamics.. as easy as rocket science. It's the dang wiring that drives me bonkers.
