93euro Posted January 1, 2006 Report Share Posted January 1, 2006 so just a little bit ago i was sitting there talking to a friend with the engine on and realized that the temp had risen to 220 and no fan was on. i went home and shoved the paperclip into the diagnostic thing and only the left one came on. im stupid, so any suggestions?

birdman Posted January 1, 2006 Report Share Posted January 1, 2006 check the relay, you have to use a paper clip and jump two connectors and if the fan comes on then its the relay, if thats not it my guess would be the temp sensor. Quote Link to comment Share on other sites More sharing options...
White93z34 Posted January 1, 2006 Report Share Posted January 1, 2006 try to power up the fan independeltly, then check the relays, the CTS might be culpret. Quote Link to comment Share on other sites More sharing options...
DiscoStudd Posted January 1, 2006 Report Share Posted January 1, 2006 try to power up the fan independeltly Or swap the plugs of the 2 fans and do the "paperclip" trick again to see if the other one powers up. The fan motors GM uses are notoriously crappy. The cheap ($40) replacements they sell at the auto parts stores aren't much better... Quote Link to comment Share on other sites More sharing options...
1990lumina Posted January 2, 2006 Report Share Posted January 2, 2006 You guys are just lucky your engines get warm enough to turn the fan on IIRC the right side only comes on with the A/C Quote Link to comment Share on other sites More sharing options...

Bossman429 Posted January 2, 2006 Report Share Posted January 2, 2006 When I messed with the fans on my old (TurboSedans new) TSTE. I paperclipped the ALDL. swapped relays from fan to fan Used to test light on the none working fan to verify it was getting power. Replaced fan I could have skipped messing with relays by simply testing for power at the fan plug, and working backwards from there. I think you have to replace the fan motor and fan blade together, at least that was the case for the TSTE. You're lucky though, I spent $120 for one fan. Hopefully a regualar W fan setup is much cheaper. Quote Link to comment Share on other sites More sharing options...
ExZion Posted January 3, 2006 Report Share Posted January 3, 2006 Im having the same problem with my 1994 Cutlass Supreme with a 3.1. When sitting in the car the left fan comes on with the a/c but the right one never comes on. Even when the car's temp goes to around 220-230 and the check gauges light come on neither fan kicks on. I was wondering about just jumping the relay so that the right fan turns on at start up? any Problems with doing so?? Quote Link to comment Share on other sites More sharing options...
