i replaced the relay the switch and the fan is brand new. it worked last week so what should i check to fix it. is there a short any were?common place to check? any body asle had this prob please help me out. it is a 1991 camaro v6 thx please help

 

cheak the fuse and all plugs there is also a sensor on the block that tell the fan to turn on cheat that wire it could also be neer the rat hose on intake

 

The sensor is on the rear of the passanger side head. To make sure the fan is working, take that wire off the sensor and ground it to the block, the fan should come on. If it does then your sensor is more than likely bad, if it doesnt then your wiring is messed up somewhere and you will need to use a wiring diagram to figure it out. Also check all the fuses.

had the same problem with my IROC. The power wire to the relay is protected by a fusible link. Well the link fell apart in my hand so that was my problem. I forget which color is the power wire, it's one of the thicker ones.

 

Mike,
Where did you find the fusible link? I think I have the same problem with my '88 GTA. I just bought it and the primary fan was hot wired to the fuse box. I removed that wire and I tried grounding the green/white wire off the relays according to a diagram I found in the tech section and the fans still wouldn't run. I think I might not be getting power to the fans, eh?
