Okay, here goes another one. So i open the car door tonight and the red temp light (overheating) flashes with the service engine soon light, the heater stops running, and the lights turn off for a moment in the cab. one full second later, heater fans start again and all is normal. didnt happen every time i opened the door, but it did happn twice out of 5x i kept trying to recreate the symptom. for lack of a better term, WTF? :roll:

Re: weird new symptom just started today when i open the door

Sorry i meant to add that this all occurred when the truck was running. i was in it and went to get out, and that's when the stuff flashed. when i got back in, it didnt do it, but then it did it again when I got out.

You need a young priest and an old priest. :mrgreen:

THat is the oddest one I have heard of. Have you run the electrical tests in the sticky yet to rule out battery and alternator?

That has happened to me as well, it's like a complete BECM reboot, even the lights went out for a second while going 100-120 km/h (60-75 mph) at night on a dark country road (very scary......).
Since replacing the fuse box it didn't happen while driving, but when a passenger (passenger sits on the right side in my case) opened the door/got out it happened maybe 3-4 times in a few months.

I replaced the alternator a week ago, I'll see if it comes back (maybe it happened due to a wet BECM, o-rings were leaking).

Re: weird new symptom just started today when i open the door

Hi there Munichp38a,

I had a strange fault in the electrics a while ago. The dash indicators would go nuts!

It turned out to be some self tapping screws under the driver's side trim.

Pop the trim off the carpet and have look for anything that might earth out :wink:

I hope this helps 8)

Cheers,
Mick.

The difference between our cases is that on yours the drivers (left) door illuminates the christmas tree, on mine something on the passenger (right) side freaks out the electronics (it already happened when I was taking something from the passenger seat while driving)

I have started to dry the carpets using a 500W halogen flood light, you just have to be extremely careful not to melt anything (luckily I only damaged a very small area :doh: ), but there was a lot of steam coming from the carpets...

Whenever something like this happens i like to leave the battery disconnected overnight. Fixes a lot of problems.

Good idea, i'll give it a shot. i thought it was something related to the remote starter that the previous owner had installed. It hasn't happened again since the initial post.
