The 83 GL verticoupe is coming along-but I need Help! - been working on my cooling system trying to get my cooling fan/thermoswitch situ figured out, now my heater blower has quit working all at once. Removed the fan and hot wired it -it turns just fine, the fuse has power w/key,... I've been thru Alot of threads, and can't find any relay under the dash where they are described, just one for the headlights, and the wiper thingy. Near the coil I discovered 3 relay doohickeys, one of which is funky-that runs the AC fan -don't know about the others, but I think those are cruise, and something else with a weird plug.
Can some one help me find if there is a relay on this car?

Check the connector at the fan. The Green/white wire in the connector should have 12v w/ key on.

if it does, problem isn't the relay. problem would be in the reistor pack, mounted to the far front of the heater box, drivers side.....could be unplugged.....if it was just bad, you'd still have speed 4.


If it doesn't have 12v, then probably is the relay.

relay is up in the dash, drivers side.....look for the one with a fat white, and a kinda fat Green/white wire.

Please, if someone could put up a pic of where the relay is -I swear there is nothing I can find -and where is this resistor coil thingy? is it all the way at the firewall? how to get it out?
I've got no power at the fan pigtail, and I don't see the four relays everyone refers to on the drivers side -I can post a picture if someone can point it out..:banghead:

Sucker- thanks so much for coming thru for me! I was at a loss. Is that a Bently book?
I didn't cut power, so when I opened the fuse 'capsule' the thing had disintegrated -and the bit of wire bridged the hot to something else and quickly burned up the insulation all the way up to the big harness, -smoking while I pulled fuses and tried to get it free!!,:eek:
Anyway thanks again for your help :headbang:

glad to help. Yes Bentleys manual, the best one of all. Not as vehicle specific as a FSM but easier to use and somehow just as complete for most things.
