Twice now I have had my AC fan continue to run after I switched off the engine/ignition after a drive. Managed to switch it off by turning engine back on, turn blower to normal air (once or twice) and switch off engine (1-2x).
The AC has recently had a new evaporator and drier and works fine. The problem does occur randomly.

Any ideas on where to look for the cause?
XJ 97 auto 4.0 ltr 6 cyl

 

I have an idea. My girls '02 did exactly that. I 'think' it was called the aux fan control relay? Blast my memory.. anyway, it wasn't a regular relay, like in a fuse box.. it was behind the pass side headlight, bolted to the body (kinda hard to get to) but if you follow the connector on the fan itself to where it disappears behind the headlight, you should find it. Sorry, I can't recall exactly what it was.. it seemed to be a common part to fail. Hope this helps.

 

Well, at least it gives me something to check out.
And once again the confirmation that "your problem with a Jeep, is never your problem alone, somebody had it before you" once again appears to be true
I'll go look for it. Did you replace the relay?

Edit: '02 you said? You probably are talking about a Grand Cherokee and not a XJ then?
