Okay team. With the heater on I get a bad smell. It smells like burning almost like a welding slag smell. When outside the car I cant smell It. Only inside the vehicle. It gives me a headache so I need to figure it out. Thanks
Just a wild guess, is your blower motor working? Could be an overheating/burned up motor.
I'll guess a heater core starting to seep. Hot used coolant and MIG welding smell similar now that I think about it........
Lapoltba. i think hit the nail square on the head
The motor was working when I got the smell. I pulled the resistor and it looked like it was working hard. One of the coils was crispy looking. I decided to replace the motor as I suspected it was over drawing. Plugged in a new motor and wheel and all is good... other than the lingering nasty burnt electrical smell.
