Sherlock Bill Posted April 8, 2022 Report Share Posted April 8, 2022 A while back my turn signal had on again off again functionality. I went to YouTube for tips. The consensus was to spray contact cleaner into open seams in steering column around turn signal lever to blow out dust and dirt accumulated over the decades. I blew out with blower end of a vacuum first and then used contact cleaner, working the lever up and down. I still had the same problem. I took the truck to my mechanic and it turned out to be a simple change of a plug in part under the dash. He used NAPA Thermal Flasher 552 which replaces 536 or 552 according to the package. Hope this tip will help someone else. 1 Quote Link to comment
