Question about 2002 Jeep Grand Cherokee
I have an 02 grand cherokee. I start the car in the morning, turn defrost on, but it doesnt do anything. I have to drive for about 1/2 an hour before it starts blowing. Its the same with the heat and AC. the longer I drive, the better it works. It seems to me that the harder I push the gas, the warmer it blows. any suggestions?
If your ac blows hard and cold then it could be your heater core, but most likely the thermostat is going bad. When those fail it leaves the radiator in an open position and all your coolant goes through your radiator, so when its cold out its hard to get warm air out of your heater. IF it were my jeep i would take it somewhere and have the radiator and heater core flushed and check the thermostat. IT can be done yourself but requires some flushing agent from auto zone or auto parts store and some time and auto knowledge.
