My 2001 T&C had a check engine light.

I took it to a very trusted mechanic.

The code was for the fan relay, he checked it, it was shorted. he replaced it but the code was still there and the fans did not come on.

He spent a couple days checking all of the circuts, grounds, relays, senders, etc.. and determined the PCU had an open circut in it.

He estimated replacing the PCU would be $1200 and that a used one would be more trouble than it's worth.

His plan B is to hard wire in a temp sender to the fan relay. Is there any down side to plan B?

The van has 168K, a new compressor, evaperator, condenser and trans in the last 20K (2 years). I really want to get the full goody out of the trans.
