I recently got a 2000 Mercury Villager Estate. Most of it runs fine - AC, interior lights, headlights, etc. Some of the electronics -- radio, windshield wipers, some of the power windows (I don't believe the driver's window has this problem) -- only work when the vehicle is in accessory mode OR at seemingly random intervals when it's driving (all or nothing though - if the radio works, the wipers work). One interesting feature to me (who knows very little about cars) is that the clock display on the radio works when I push the clock button no matter what (maybe it's on its own battery), but will stay on when the electronics are all working - that's how I've been visually noticing when it's working or not.
So far (I've had the car for 2 weeks and driven it lightly) the electronics have worked 4 times that I've noticed, maybe yall can see a pattern:
- When I had it parked in the sun all day (about 105 degrees F, UV index 9), I immediately turned it off, startled by the radio, and turned it back on and nothing was working again.
- When I had it parked in the sun for about 9 hours, everything worked throughout the whole drive.
- When I got out of the store after shopping, it worked the whole drive back (but wasnt working immediately before I got into the store).
- Halfway through a drive back from the store; it wasn't working when I left (I specifically checked, as my brother was in the car and I was explaining this problem to him) but I noticed the clock was on halfway through and everything had started working.
I was thinking maybe a loose wire going to the ignition switch, but I have no clue. I don't much care for radio, but the windshield wipers, on the other hand...
Thanks in advance
