ZX AURA - 1993
My Heater has packed up. The Fan has stopped running on all 4 speeds, I have checked fuses in the fuse board but all are OK. Is there an in-line fuse? Any hints would be appreciated.

Have the same problem with the fan in my ZX 16v 1993. Yesterday, just after starting the car, i saw/smelled smoke pouring out from the vents. And now it doesn't work. Traced the fault to the slighlty burned<img src=icon_smile_shock.gif border=0 align=middle> fan motor. Strangely this incident didn't blow the fuse..?
This heater motor problem is/was quite a common problem, its caused by water ingress into the heater motor.
Under the bonnet, behind the battery on the LH side of the car you'll see that theres a plastic grille over the top of the inner and outer bulkhead. Look down here and you'll see that the wiring loom runs through a foam gromet. You will also very likely see that theres a lot of water here, especially if its been raining, or you have recently washed the car. This water seeps through the bulkhead down behind the dash, and into the heater motor, causing it to eventually burn out.
To stop this happening again, enlarge the hole in the foam by the wiring loom as much as possible, and any water lying here will drain harmlessly away.Some people remove the foam altogther, leaving a 2" x 2" hole which allows the water to drain away instantly.
