Question about 1993 Pontiac Bonneville
I've taken my '93 pontiac bonneville in to serveral different shops and they all have said that there is nothing wrong with my a/c, but when my car sits in the sun for several hours on a 85 degree day and I turn on my a/c it doesn't cool down my car at all. The air feels lukewarm, and doesn't really blow alot of air out even on the highest setting.... Please help!
AC works as so..
It does not actually cool the air, however it removes the heat from it (and without heat the air feels cool). As the air is blown around the car the AC system removes the heat from the air, and then it moves it to the condenser at the front of the car (infront of the radiator).
Now usually the car is moving forward, so that air flow will cool the condenser and then you can move more heat from the air inside the car and push it out the front of the car again. This is why, if you have a front wheel drive car, you will hear the cars fan start as soon as you turn the AC on.
Also the car will be much better at cooling the air that is recirculating inside the car (your a/c system will have a button for this) then if it tries to cool hot air from outside.
The long and short of it is that if you hop in a hot car, start the car and run the ac (even at full) it wont be cool straight away, it is mostly influenced by how much you are driving forward.
Try this. Start the car, turn the AC to recirculate the air, turn the AC on and go for a drive for 10 mins, pull over and wind down the window. Compare the outside air to the inside air, then you will see the difference.
