I just got back home from a 2500mile round trip visit to Florida. The power windows have been working flawlessly.
Today I took on the power door lock issues.
To sum up the problems:
-Doors would have to be unlocked, then locked in order to lock the doors with the fob.
-security/horn would not sound when locking door with key. Also, the window roll up and down with the key in the door cylinder did nothing.
-Dome lights would intermittently work with the doors open.
-Without any speccific circumstances, the door lock system would randomly do any of the follwing. Doors would lock, and security system would go off with the doors open, the hood open, the trunk open, door open with key in ignition, door closed with key in ignition-this would happen with key in, ign off. Key in, ign on, but would not happen with car running.
-Doors would sometimes lock while driving.
So I took apart the door latch. My circuit board looked a little different than the pictures posted. There was some sort of coating over all of the solder joints. I couldn't see any actual broken solder joints , but I went over them all with the soldering iron and solder. Basically heated and resoldered everything.
Put it all back together, (Which was sort of a pain in the rear compared to other doors I've worked on) and from what I can tell, everything is working beautifully! Every function of the central locking is doing what it is supposed to do! I am very happy with this, and I thank everyone for all of their help and guidance.
Now, the not so good. While in our road trip, the flasher started acting up and would continue to click after turning off the turn signal. While it continued to click for anywhere between 2 clicks, and 30 clicks, the lights did not flash along with the clicking. I am assuming that it is the flasher, which appears to be a signal unit part of the hazard switch. I think replacing it would hopefully fix it, but of course I come here first.
Secondly- and from what I can tell the last of the electrical grimlins. The HVAC control head doesn't always illuminate when the parking/headlamps are turned on. I can get them to come on by hitting the control head. I would think something is loose or not making great contact. Anyone see this happen? Any super tips?
Thanks again for your help! I was ready to trade this car out of frustration, but if I can get all of these issues ironed out then it will stick around for awhile.
