My friend has an '01 SE and it was running well and operating perfectly. Then he had the rig detailed and now washer pump won't stop running and the right high beam light stays on. Also, the right turn signal light and side light stay lit, albeit intermittently. Only the right side.

He disconnected the washer pump and has now disconnected the battery. Otherwise the battery winds up being drained.

Any idea what is causing this?

 

Pressure washers can cause problems if the fuse/relay box was sprayed too heavy. Mine started smoking when I did mine... I un-plugged the battery and let it dry out. Everything was normal afterwards. If your friend can park the rover in a warm garage and let it dry for about 8 hours or so, that might fix the issues. If it does not, the electrical system might have been damaged.

 

Underhood fuse box may have water inside, the relays may be sitting in water. If so also remove relays and dry the base and pins.

 

Thanx for the suggestions gents. I'll pass the info along.
