I have a 2000 z24 cavalier and Im having an issue with the heater. In summary, when i turn it on it works for a short while then i can hear it dying out until it stops completely. if i turn the switch off for 5 mins (sometimes less) then back to the on position, it starts up as it should then shortly there after it starts to fade away again until no heat is being forced out, i am constantly repeating that step to maintain heat in the car.. (its winter here, nearing -30 to -50c). ive done a bit of investigation before comming here so that i may better understand the issue, and i am narrowing it down to the blower motor... however ive been plenty wrong in the past, and fixed parts that didnt need to be fixed, i hope ive given enough information and i hope someone knows what i have to do.
Thanks in advance.
