Hey all first post here although been lurking around.my wides expedition drivers seat won't heat up.the light comes on but no heat.how do I test/fix.the passengers side works.thanks all

 

A little info will certainly help, like what year?

 

I have the same problem on my 2004 expedition the switch is on the left side of the seat by the power seat control. I don't think mine has a light that even tells me it is on

 

That's not a factory location for the heated seat controls in an '04. The heated/cooled seat switch on '03 and '04 (maybe more) is in the console above the cup holders. If your seat has only heat, and it is a button on the left side by the power switches, it is a seat from another year/vehicle. The location you describe is where the control was on my '99.

 

Mine is an 01 Eddie bayed.like I said the light comes on but no heat

 

I think that is the heated wire mat configuration, the typical failure you are describing is a broken wire. If you roll the leather back (should unclip at the lower edges), you will likely see alittle burned spot where the wire is broken. I think you can buy the mat itself. If not from Ford, definately aftermarket.

 

Pulling leather sounds fun.I'm thinking a blanket for the wife will work

 

It comes right up, it's not that bad. It is stretched tightly over the cushion, but once you compress the foam and get it started it will come off easy. A little fincky going back on, but patience will get it done. The PITA is that you need to do it twice to diagnose / confirm, then again when you get the parts.

 

Neither one works in my 2000 E.Bauer. Is the heating element only in the cushion or are there elements in both the back rest and cushion. Dorman makes both aftermarket so you do not need to visit the dealer. The one thing I am trying to figure out is if it is a direct replacement. Dorman makes it sound like it is. The part numbers are 641-207(backrest) and 641-208(cushion). According to a seller on ebay, the 641-207 replaces the following FORD #'s

I had the same problem , light on and no heat . I pulled the seat then pulled the lower cushion to find broke element wires at the very back . These breaks were very easy to see as they were burnt . I just sectioned in some longer wires to give a little more slack so they don't break again . The repair was free and took about 2 1/2 hours. The only special tools needed was a pair of hog ring pliers to put the covers back on.

 

Hardest part is getting the hog rings off and then back on, well that and finding exactly where the broken wire was ...
I just pulled the whole seat out of the car when I did mine.

 

Is it possible to repair the wire and replace the hog rings without removing the seat?

 

No you must take the seat out . Taking the seat out is very easy . The Seat Shop . Com has a very good video on cover replacement.

 

Assuming you've taken the proper precautions to avoid deploying the side airbags, if so equipped.

 

OK. Thanks for the link.
