Electric fan relay?
96xj, my electric fan doesn't go on even at 215. When the ac compressor goes on it does. I know there's a relay for it. But I know it doesn't go bad that often so it's hard to find info about it.
Any help would be greatly appreciated.
Thank you!

If it turns on with the A/C, the relay is working. Same relay as for temp-related operation.
It's driven by the PCM when the coolant temp sensor indicates it's too hot. Might check the CTS. (the one in the thermostat housing). Your gauge uses a different sender, the one on the rear of the head.

Radi beat me to it and he's absolutely right.
