Help

I have a 1984 K1500 4x4. My problem is that the left rear flasher does not work when the Hazzard lights are on BUT it works when just using the turn signal!!! Any ideas as to what the problem might be????? Thanks

check for a burned bulb anywhere and get a constant load-independant flasher and you should be fine. both systems use the same rear wiring from the dash panel back, but are fed differently

Thanks for your reply I will try that. Thanks again

You may have a bad ground back feeding through the other taillamp circuit. When the flashers are on both ciruits are energized and the "alternate" path is no longer available.
