HEATER BLOWER NOT WORKING

[MArk_20012]

HI Everyone,

My heater blower was working intermitently untill it finally came to a stop. I bougth another heater blower+ resistor , fitted it in the car and it still wouldn't work. The fuse is fine. However when i tested the power supply(the one going to the heater blower, behing the glove box) with a multimeter, there was no power coming at all.
Has anyone experience similar problem?
where would the power failure be happening?

Perhaps a new control unit?

Thanks Edk, I will test the control unit and keep you posted.

Hey Edk,

still no joy. there is absolutely no power going into the control unit
-i unpluged the wire harness that hold the bleu/black -bleu/red and bleu/white wires at the back of the control unit, tested with a multimeter, and not power ran throught.
I also noticed that the the rear defrog wasn't working).

Is there a relay that controls the heater control unit?
please advise.
