I have two, first my front defrost does not get hot, or the heat does not get how unless I am driving the car, when it is idle it blows out cold air, but once I start driving it it blows out hot, but when i stop for a red light it blows out cold again. Second my front seat does not work any more, I have tried replacing the fuse but as soon as I put a new one in it blows right away. Do you just recomend getting a new main switch?

- It does not matter if the car is cold or warmed up, I could let the car warm up for a half hour and it will still blow out cold air until I began driving it, once I start driving it, it will start to blow out hot air, but when I stop at a light it goes back to cold air,

My first challenge since I became member of this site! What does your temperature gauge tell you when this is happening? For the seat, take it off disconnect the harnesses and check the cables underneath, you have a short-circuit.

- Check your coolant level, check for leaks. I think the system might have air due to low coolant level. If the coolant is low its going somewhere! I think when you are moving your working the water pump harder and the coolant is able to get to the heater-core plus the force of moving pushes the coolant to the heater-core. That's when you get the heat. Have the system flushed and refilled.
