I just bought 2001 Coachmen Mirada 28ft Class A (Ford F53 chassis) for a great price due to some existing wiring issues caused by mice. So far I've only found one wire under the dash that has bare wires and I'm going to fix this weekend, but I'm sure there are more wires that I can't see (and vacuum lines.. LOL)
The most immediate issues are headlights and turn signals.
Problem
- The passenger side low beam headlight doesn't come on with either DRL or low beam.
Working
- Driver side low beam.
- Both high beams work fine, though they are wired completely separately and in different sockets.
What I've checked
- I've checked the bulb and it appears fine, actually looks brand new.
As a chance the bulb may be bad, I'll use a test probe this weekend and see if 12v is getting to the bulb. If no/low voltage is hitting socket, I'll trace it best I can to where the other headlight splits off and see if I can find a bad wire.
Second issue, turn signals are having issues.
Issues
- Neither front turn signal bulbs works at all. They are mounted in the mirrors and are integrated into the mirror body itself. I used a multimeter and tested voltage using pos/neg posts in bulb casing, they show as .3v...
- Passenger side turn signal doesn't blink, rather shows as a solid tail light when the switch is activated for that side. When signal is turned off, lights turn off.
- driver side dash arrow is solid and never goes off... whether the signal is on or not.
- passenger side dash arrow never comes on at all, whether turn signal is on or not. Bad bulb in cluster for arrow?
Working
- Driver side signal blinks as normal.
- Emergency flasher works, but other dash lights flash with the ticking of the flasher.
- Signal flasher works fine.
What I've tried
- Changed out all rear bulbs with brand new bulbs.
- I switched out the signal flasher relay as a test with an aftermarket one, same behavior.
- Removed and examined the turn signal switch stalk. Apparently some develop a green oxidation inside, mine appears fine with plenty of dielectric grease inside.
Could the turn signal switch stalk be bad on the one side? Obviously the turn signal wiring in rear is OK as the emergency flashers work fine on their own. The solid tail light sort of point to the switch, does it not?
Any ideas?
