Car is an 05 XLR. When I push the wiper switch down for a single swipe, it doesn't return the wipers to their correct position. whereever in the cycle I let off the switch is where the wipers stop. Any ideas?
Bad wiper motor? Is there a positioning switch that could be bad? HELP ! It's the rainy season in KC and I just bought this car. Of course, it was a sunny day when I bought it and never that to test the wipers.
If you're lucky, it's the switch. Depending on how handy you are with a multi-meter and a schematic, you might get real lucky. Otherwise it's off to the dealer to have them connect a Tech II and diagnose the fault, which could save you time and money in the long run. There are 23 modules in the XLR connected by two bi-directional busses. Without a Tech II, you're very limited in what you can do to repair this car.
The following diagnosis might be helpful if the vehicle exhibits the symptom(s) described in this PI.
Some customers may state that the wipers will not park after using the wipers in any position. The customer may also notice that when using the mist button, the wipers will stop when the switch is released and mist function will not continue to wipe windshield and park.
Check the wiper on/off relay (relay #45) in the Underhood Buss Electrical Center (UBEC) and make sure that the relay is properly secured into the socket of the UBEC. If the relay is secured, try a good known relay from a good known vehicle and replace as needed.
Please follow this diagnostic or repair process thoroughly and complete each step. If the condition exhibited is resolved without completing every step, the remaining steps do not need to be performed.
