Question about 2002 Jeep Grand Cherokee

My ac turns on but it only throws hot air it used to throw it cold a few days ago, whats the problem?

Well it was throwing cold air before but when i got on the freeway and go over 65mph it would turns off for a while then it would come back on and not throw that much cold air, today i added a can of A134 thinking it might be that but after that it is only throwing hot air?

Adding a can of freon is not the solution, a system that has too much freon will not work right and there is a chance that you will damage the compressor.
There are low pressure and high pressure switches at work when the system is operating.
You might have a bad switch, leaves or other matter blocking the front condenssor.
Is the system actually full?
It's best to give this problem to a certified A/C mechanic.

2004 camry ac light blinking and throws hot air. Suggestions?


My 2003 Toyota Camry AC often starts blowing hot air and the AC light starts blinking. I don't know why the following process works, but it does. Using the temp selector (left) reduce the temperature all the way down to Max Cold and then push the Auto button. It will start blowing out very cold air. After a little while push the temp selector to the desired temperature.

sounds like you have a leak concern if they are adding freon

however, it also sounds like a restriction in the system and/or a defective TXV

do you have pressure gauges... this is the only way to diagnose an a/c system without just throwing parts at the concern

1997 Nissan 4 cylinder truck AC works excellent throwing snowballs cold air, then it will blow hot air. Relay switch and clutch has been replaced....Did not fix problem!


sounds like compressor isn't working properly or heater vacuum is opening vent to heater core.try turning on ac and if it cuts on and off repeatedly every few seconds the freon level is not correct or high pressure switch may not be working make sure radiator fan comes on when ac is on.if all this is working properly check vacuum hoses to heater may be opening vent doors to heater.hope this helps

Ac not throwing sufficient cold air


I would try recharging the system. if the recharge doesn't produce could air, this will confirm a compressor failure.Inspect the clutch function. the AC clutch should click when it is engaging the compressors actions.

It sounds like your heater core is stopped up, or be sure your coolant is flowing, and picking up heat from your engine...Thermostat, water pump, etc.

Air Conditioner blows very hot air


ASE mechanic here:
sounds like a mode door is stuck causing the air flow to go across the heater core only and not the evaporator. try activating the hot to cold functions to may be un stick the doors. if no changes then try a computer scanner, these new cars can have HVAC control codes and be accessed with a scanner, telling you the problem. if no access to that a good European shop is the next best thing. They might be cheaper than a Porsche dealer.
