Here's the deal....
I have already replaced the flasher relay, multi-funtion switch, and have checked all the fuses, still no luck.
The problem started one night after getting my oil and fuel filters changed. I got back from the shop and put in the street program from my new SCT programmer (the first time I've ever used it). After that, I have had no turn signals!! Is this just a coinsidence, or could the program have something to do with the problem???
Thanks in advance for anything else I could check before I give up and take it back to the shop $$$$$
