Heater Blower Relay?
Hi,
I'm told there's a heater blower relay in the engine compartment? Can anyone post a pic to it please? I need to check that a couple of pins are jumped on it, which allows my footwell auxiliary blowers to function permanently without the engine compartment blower. Also, should the footwell blowers stay on, when operational? Mine seem to intermittently work  Does that mean they are on their way out?Thanks in advance

The one in the middle with 3 holes on the left & the defogger relay on the right.
If both of your footwells are intermittent at the same time, then I would suspect the relay. Ian

Cool, thanks!
Any idea which pins need to be jumpered so the footwell blowers can be powered by the centre console switch?

This is the wiring that has been posted:
Terminal 12 - Hot from Front Fuse Panel "key on" Terminal 7 & 8 - Hot from Fuse 2 (Rear Panel) Terminal 3 - Hot from Fuse 1 (Rear Panel) Terminals 5 & 6 - Output to Main Blower Terminals 4 - Output to Heat Controller (the dreaded Footwell link) Terminal 2 - Ground I have not confirmed it. Ian
