Hey guys,

Used to have a problem where I couldn't ever use wipers on high speed, didnt bother me since thats rarely needed, but lately now my wipers wont work at all.

I tried swapping the relay for wiper Hi/Low and Wiper on off (72 and 73) with a backup to isolate which one is bad, but it seems like theyre all bad, I go under the hood, play relay bingo for a bit, then theyll start working again, until they dont. Any ideas apart from just getting 3 new relays? It doesnt seem like a relay problem since all my swapping doesn't resolve the problem.

 

 

Just replaced a Buick Encore Wiper Motor over the weekend. If it is not a fuse or connection/harness issue, about 75% of the time it is the Wiper Motor, the other 25%......... the switch arm.

 

Good point. Just find the signal loss! KOEO, WIPERS ON, wiggle/reseat/rotate:connectors/relays/switch. Warning: don't leave the wipers on a dry windshield or you will cause damage to the wiper motor/transmission. When you find the source of failure, open a can & clean contacts.

 

got some new relays and problem seems to have resolved itself, my starter relay did go recently so maybe they all decided to

solved for now

thanks for the help though guys

All my '07 relays are oem! Inspect the fuse box:
