Turn signals only work with headlight off
OK so I have this problem i cannot figure out. Recently since winter hit i have been driving my jeep more. I have noticed that my blinkers work fine with no problems. When i turn on my running lights and headlights they do not work. They light up but do not blink. I have checked the lights and the only light i have out is the rear brake light. That will be fixed in the morning. So any ideas on what it could be, what I should check?
One other question. My blinkers flash about every 3 seconds when i have them on. Is that slow for them?
The jeep i have is a 1990 Cherokee pioneer.
Once again thanks in advance for any help.
