Over the past few weeks whenever it is colder out and my truck has been siting outside for awhile, when i start it up i get the door ajar warning and it wont go away no matter how hard a close the doors. After the truck has warmed up for it goes away and doesent come back until another colder day. Its been doing this once the temperature drops below -10 deg celcius here in winnipeg. Has anyone else experienced this probleme?

 

Since we're talking about a switch here...I'd say maybe it's getting stuck. Maybe there's grease on it and the grease is getting sticky/thick when it's cold out...and so it sticks in the position that makes it think the door is open. Only problem with that theory is that you'd think if anything, it would stick in the OFF position...not open.

 

It's probably just a sticky door jamb switch. Try shooting some WD-40 at it and see if that solves it. Otherwise take it to your dealer and use that warranty.

BTW another theory is the wire on the switch is grounding out and giving the warning. That wouldn't explain why it happens only on a cold day here in Winterpeg, Manisnowba though.

 

Just a comment, there is no doorjam switch on the f150 trucks. It is built into the latch mechanism!

 

Same difference, it always happens on rangers, and wd-40 solves it.

 

The 'other' forum has dozens of threads on this issue and WD-40 on the switch works about 99% of the time.

 

I have an '94 f150 and it has door jamb switches. as a matter of fact i am trying to find one for the driver side since it is broken.
Does anyone know where i can get one on the internet?

 

I had this problem once in the first few months I owned it. And it was freezing outside. It eventually went away and never happened again.

 

Wd-40 is the answer, this has happen to many people here.
