yes, the door ajar switch is in the latch, I have "fixed" several of them in the past (mostly on taurus's) by just spraying some penetrating fluid in the latch, and working it for a bit, in fact, out of the dozen or so I've seen, Ive only had to actually replace 1, dont even take the panal off, just spray directly into the latch and work it back and forth.

94 Jeep Grand Cherokee Electrical Puzzle (Radio - Interior lights problem) by 94grandcherlar

When any door is opened or the dash lights dimmer switch is pushed to ON, the interior lights come on but many other things don't work - radio turns off, pwr locks, map lights don't work. Another piece of this puzzle; when the key is turned off then turned on again later, the radio resets to 12:00 with the stored radio stations still there, but not any "recently" saved/stored radio stations. The radio is the original unit and I'm not aware of any electrical issues from the previous owner.

Headlight Dimmer Switch
GM Blazer/Jimmy/Typhoon/Bravada 1983-1993
 
REMOVAL & INSTALLATION
 
   1. Disconnect the negative battery cable.
   2. Remove the lower column trim panel, then remove the steering column-to-instrument panel fasteners and carefully lower the column for access to the switch.
 
If the ignition switch shares fasteners with the dimmer switch it may be necessary to remove it first.
 
   3. Remove the dimmer switch-to-steering column retainers, then remove the switch from the column.
 
To install:
 
   4. Position the switch to the column and loosely install the retainers.
   5. Insert a 3/32 in. (2.38mm) drill bit into the adjustment hole provided in the switch to limit travel, then push the switch up against the actuator rod in order to remove lash.
   6. Tighten the switch retainers, then remove the drill bit.
   7. If removed for access, install the ignition switch.
   8. Raise the column into position and secure, then install any necessary trim plates.
   9. Make sure the ignition is OFF, then connect the negative battery cable.

I have a 1995 mitsubishi eclipse, and recently it started doing this thing where i turn the car on and at idle everything works fine the car heats up to the temperature it should be at and the heater works great, but right when i start driving the Temperature gauge goes down and my heater gets cold.. but once i put it in neutral it starts acting normal again..anybody know whatt to do?

Sounds like at idle you have a high vacuum situation but when you drive, the engine vacuum goes down...if your heater valve is vacuum controlled or if the various flaps that direct heat in your car is vacuum controlled, I'd guess you have a vacuum leak somewhere and your heater valve is closing as you accelerate.
 
You could test this theory---if you are driving down th road with a cold heater, put the car in neutral and just coast with your foot off the gas---if the heat goes back on, then there you go--you have some vacuum issue.
 
If it isn't that, I'd check your coolant level. Have you added coolant lately or opened up the system? If you did, you might have air in the cooling system that needs to be bled out. Low coolan might also give you this problem.
 
I don't think the thermostat could cause this, as you wouldn't have heat at idle with a bad thermostat if it were stuck closed....or if it were stuck open, you'd have heat idle or high speed.

Hi, I am Alex.I wonder if somebody can help me to solve the problem of my 1998 Linconle Continental. I do not know why the alarm system always alarms in the night without any reason. Somebody told me that it is because the low temperature. I sincerely hope that somebody here can tell me how to let the car stop alarm without any reason.

My 1999 Pontiac Grand Am SE 2dr 4cyl automatic transmission is messing up. When I open a door, bump in to it, turn it on or do anything that involves electricity the car lights start flashing and clicking and if I hadn't turned of my alarm horn it would beep sometimes. It will even start flashing when I come to a stop light, and the engine is still running. It does this every time! My pass lock light on the dash is constantly FLASHING. This all started happening a few months ago when I let my friend drive the car and the battery just died, I replaced the battery Did I completely mess it up and is there anyway to stop the flashing and clicking? It is driving me crazy. I have to turn my headlights on during the day so people will not think I stole the car. Is this my passlock? I can start my car every time and the passlock light is FLASHING not staying on constantly. Can I expect my car to stop starting any day? We tried to cut the yellow wire attached to the ignition but it didn’t do any thing because I can start it every time so I doubt it is my ignition/ignition sensor. Please help I don’t have the money or want to spend it on a dealer fixing it. I keep reading about installing a remote start to bypass the passlock but my car STARTS. What do I do?
