    Heater and Blower Problems

    I can't fiqure out what is going on I've searched the board and still can't fiqure it out. My Blower is constantly on high and cannot be adjusted and my heater is blowing cold it sometimes starts working after about 20 minutes. My coolant level is OK and I replaced the thermostat and it made no difference. The testbook symbol is on, so what do you think? BTW there is no water in the footwells.

    Have you checked and/or swapped your relays?

    Your description of the problem is not very clear. What do you want your system to do?? What are your settings??

    If you want heat and get it only after 20 minutes you might have a flow problem in your heater. Air might be trapped or coolant level might be low.

    You can not adjust your blower speed? Is it in manual control mode? If so then the small copper fingers at the inside of your dial might be broken off.
    Or there might be a wiring problem towards your blower motors.
