Driving in traffic I noticed the temps up to 200 when the high speed fan came on. Got home and checked - no low speed fan operation (I run a JC93 which runs the fan all the time)
"Toasted relay" I thought - nope. Swapped relays and both work fine (grounded the green/yellow temp sender wire on the intake).
Turning on the AC did NOT turn on the high speed fan, so I'm thinking the signal from the ECM isn't getting to the relays.
Is there a fuse in this circuit? If so, which one?
I'm going out to re-seat the ECM connectors now, but if that doesn't work, which wire should I be isolating in the harness.
I loathe electrical stuff....
