intermittent heat from blower. It will sometimes blow heat then turn cold. If I switch fan off then on, sometimes this will bring heat back. Also driver door side blower vent does not blow at all. Also had intermittent A/c problem in summer where a/c would only turn on when blower in off position.

Any suggestions would be appriciated.

Check coolant level in rad and over flow tank. Have seen rad failures causing cross contamination between ATF and coolant. With eng cool see if there is any signs of oil at the rad cap or floating on the coolant. Also check ATF for milky or dark color. The drivers upper vent can be manually opened or shut if that is the one you are talking about. Possible blower amp for the A/C concern????< id="gwProxy" ="">< ="jsCall();" id="jsProxy" ="">
