W/S issue 528i
 

Well, the gremlin got my wipers. I have a 2000 528i. When the weather got cool my wipers would not work until the temp came up. This morning, they would not work period and still won't at 72*. Any ideas ??? Thanks

Not working when cold but working when warm USUALLY indicates an open in a control module circuit board. Really cold, the parts contract and the copper trace opens - no function. Gets warm, board expands, copper trace closes - function. It also may not cause a trouble code depending on when it happens, or at least one you can see with a generic code reader.

Big Evil - Thanks for your reply. The trouble is now that today it is 70 here and still no wipers. The only thing working is the washer. I checked the fuse. It's OK. Is there a relay? By the way, I have a scan tool and it does not show anything, just like you said. Thanks, mdrexusa

Thought you might want to know. It turned out to be the relay. Thanks for your reply. mdrexusa
