ok I have a messed up problem with my 78. tonight when I went to leave with it I went to use my turn signal and they wouldn't work not in the dash and not outside it would also turn the stereo off when I pushed them on. then as the bronco warmed up they started to work but would go really really slow still shutting the stereo down for a second then it would pop back on. once it was fully warmed up I had no problems at all. stereo worked fine turn signals worked fine. seems really messed up I know and I hate trouble shooting electrical problems. I didn't think cold affected wiring and stuff like that or does it? Any ideas?
