Headlight Switch or Wiring Harness?

Ok learning more and more about my 2000 each day (seems to be a lot today).

Took it to the stealership due to a burning smell at night, turns out the owner before me had the after-market fog lights installed and connected directly to the headlight relay, switch, etc. and was causing it to overheat (needed to have a separate relay). Now the headlights blink off periodically after they have been on for a while. Might this be the actual switch that had been damaged from overheating (that's what the dealer said) or might it be the wiring harness to the headlights (maybe both?) How difficult is it to replace both of those parts?

I don't know if this is a related symptom or not, but the left turn signal will not stay on. I'll turn it on and it works, but will miss a "beat" every few seconds. Maybe this is something separate that the dealer screwed up?

Thanks again

You need to inspect all the headlight components to determine the cause of the problem. Without knowing the cause of the problem, there is no way to determine the needed repairs, costs, parts required, or the work involved.

Replace the blinker module. It is an EP-27 at the auto parts store.

As CJ7-Tim said .... its pretty hard to guess which component is the problem without inspection.

The headlight switch, the socket it fits into ... and even the engine bay harness connectors are typical issues tho.

Might be worthwhile doing a headlight harness upgrade as well while you've got it in bits ... the factory setup is very light duty and even brighter headlights will cause issues over time - let alone hooking up additional lights direct to the factory wiring.

This writeup link is pretty good ..... the relays however, should have both output pins marked as 87 for the diagram to be correct ..... http://fitchva.com/jeep/?p=48 .... or theres premade ones available.
