Does anyone know the location of the clutch relay for the 2008 Cayman XL?

I have power leaving the pressure switch up front but the Cond. fan and clutch will not energize. I'm sure the problem is with either the relay or a bad fuse.

Usually the clutch relay for the a/c is in the fuse box, look in the engine compartment

What chassis?

I did and I don't think it's there, also, it's a Roadmaster chassis

It may not have a clutch relay.

I believe on my 2008 Knight no clutch relay is used. power goes from the fuse to the dash controls to the pressure switch and then to a parallel connection to the clutch and fan. parallel connection was located in a plug near the a/c compressor. some ware I have a diagram of this circuit.

I found the wiring diagram for my Knight There is a fan clutch relay located in front run bay electrical box. also has separate 20 A clutch fan relay fuse in same box.. there is also a separate fuse for the control circuit that goes thru the dash controller and the pressure switch. that could be the reason you have voltage at the pressure switch and not at the clutch.
