Re: Problem with Radiator Fan???????? Please HELP

You where talking about the hydraulic fan for the WJ, but if the car has the hydraulic fan, then there is no other.
There could be an electrical fan on the radiator combined with a viscous coupling fan mounted on the engine pulley.

Re: Problem with Radiator Fan???????? Please HELP

I may also be having a problem with my '02 GC hydraulic fan. I am getting a P 1499 fault code. Says its the hydraulic fan solenoid. Dealer parts guy not familiar with it. Says there is an $80 relay in there somewhere, though... Don't want to shotgun this problem. I found the solenoid and info on the internet about changing it, but no reference to a relay. Any thoughts or advice?

Re: Problem with Radiator Fan???????? Please HELP

As far as i know the solenoid is wired directly to the PCM, so there should be no extra relay in the system. So the solenoid can be inop, the solenoid connector can be dirty or a wiring problem.

Re: Problem with Radiator Fan???????? Please HELP

The relay is only applicable for those WJ which have the electrical cooling fan. It is in fact not a simple relay, but a Pulse Width Modulated control relay which allows for multiple fan speeds.
In case you need it, the hydraulic fan control solenoid P/N = 05102210AA
