Fan relay

[TKMBUICK]

Which relay on the driver side fender is the fan relay there are two that look the same how do I no which one it is???

Both. One is for high speed and the other is low. One (low speed) is ecm controlled and the other (high speed) is triggereg by a sensor.

Ok here's the deal my is't working and I bought a new relay for it now do I need two???

No phun intended but the real way is to test a few things to determine what the real problem is.

Do you have the means to make a jumper wire? Just a small piece with the ends stripped.

Assuming you meant my FAN isn't working, you need to troubleshoot it to figure out why... likely a simple relay replacement won't fix it... here is a site that offers a pretty good troubleshooting guide:

Vortex Turbo Buick Performance

click 'troubleshooting', then 'fan circuitry' .... that should get you figured out...
