Omega Electrical and Audio Help / Re: A/C Blower Fan Relays

Smart money is on the blower series resistor being u/s. It is a bit more than a resistor - I flicked the small plastic cover off and there is a pcb inside. Also the live feed to the resistor is a direct feed to the output to the motor so I presume the control circuit is u/s unless it controls on the -ve side. £100 to replace from http://www.vauxhallworldparts.com/partsearch/partdetail1.php?partid=463 .
Interestingly they call it a heater blower regulator which probably explains where the "relays" are.

Omega Electrical and Audio Help / A/C Blower Fan Relays

« on: 28 March 2009, 19:37:41 »

The interior heater fan on my car, 1996 2.5 CDX with ECC, has decided it doesn't want to switch off at all even with the ignition off. To stop it I had to pull fuse F33. The wiring diagram shows two relays K6 and K7 which may be the cause of the problem. However, I cannot find them. Does anyone know the exact location of these so I can check them out ?
