Question for my buddies truck problem:

When the truck is running the dash light saying door ajar stays on all
the time and the interior and bed light come on when ever I slow down or
stop. After shutting the engine off, the interior/bed light stays on for
as much as a half hour.

 

Hey Cheetah Daddy....

I have experienced the same problem. I spray a little WD40 in where the plastic doo dad goes into the door (not the rubber accordian tube) and open and close the door a few times.

Ford replaced my switches one time and I've read some of the guys use the WD40 method. It seems to work. The problem, I believe is corrosion on the switch contacts.

(By the way, do you know who this is?) I'll give you a hint... yellow '01 Honda 400EX quad.

WD-40 worked for me.

Hey Steve..... back to the basics .....WD40.
By the way, the "buddies truck" is Paul.

 

 

I had the same problem, along with OD light & spedo quit at low speeds. Took in to have the sensor replaced, & ended up with a new tranny & radiator, & a $3800.00 bill. The service mgr. said the radiator is not big enough to cool the tranny. Was a problem in 99 & 00 models & fixed in newer ones. I am looking for others that may have had this problem & if they got stuck as I have.

 

WD 40 works great on the '02 work truck.

 

I just encountered this same problem on my 99 F350 CC. I have not had the problem again since the WD40 application.

 

Hey Bo , did you have an automatic or was it the 6 speed???fd

 

Automatic. Any ideas?
