Is the 1st fan speed and after-run pump work with the same relay?
I know that 1st speed from fan will come on when:
- Climate Control is in any postion EXCEPT ECON
- After-run temp switch with ignition off is activated( In this case, the auxiliary water pump will also be activated)
But, do these 2 actions are done thru the same relay, or is there a separate one for each action?
Thanks

On my 5kT, the 1st speed fan relay is in the fuse box under the hood....and the after run relay is located in the 2nd aux fuse panel directly below the steering wheel.
Actually...the after-run relay is not a relay at all, but a control unit enclosed in a 2-3 in. tall relay case. I think the original is brown, but the newer replacements are black. Can't quite remember....but either relay #324 or #271
