- Servicing the regulator can be a DIY job but you need patience
- My Ford dealer had the best price on the part I needed
- Doing this job with the window stuck at the top is a problem
- You can mash the mirror connector in the door if you are not careful
window would not move
My driver side front window stopped working in the UP position. It turns out that it is difficult to get the window regulator (the motor and the whole assembly) out of this car with the window stuck at the top. I don't think that I could get the motor out by itself without removing the regulator from the door. This is about how I did mine and some interesting things I found out.
My driver's window gets a fair bit of use. It is the most used of any of the windows. I open this window often to get fresh air while driving unless I am at highway speed. I have the auto option which allows me to one touch up or down. The window has worked flawlessly until last winter when it refused to go down. Not working seemed to correlate with the cold. When it was very cold, the drivers side window would not go down. Then, as the temperature rose, the window would start working again.
"Probably some moisture getting in there and freezing" my local mechanic Dave said. The whole winter went by like that. The following summer of 2015, the window worked flawlessly. This winter, sometime in February, the window stopped working. The car is now three+ years old and out of the standard warranty - I know this because the air conditioning compressor died last fall and Ford would not cover the $1300 bill. I was determined to take my best shot at fixing this problem. I had taken doors apart before! And there was YouTube and the internet to help me!
removing the regulatorthis one by Jason. It's clear except that the black door panel he is working on makes it sometimes hard to see detail. My door panel had never been removed. I found the fasteners at the bottom of the door difficult to separate.
My problem was with removing the regulator from the door.
Ford's service manual says to do this with the window part way down. This is so that you can reach the two clips which hold the glass. The glass must be removed in order to take the regulator out of the door.
My window had stopped at the top and did not respond to the switch. Several web sources suggest tapping the motor while pressing the window DOWN button but this did not work for me. I removed the four bolts holding the ends of the regulator tracks and was able to lower the whole mechanism and the window slightly but I could not get at the clips holding the glass. There did not seem to be screws in the window track clips but they were way up inside the door I could not see or feel so I did not know what sort of clip I was dealing with.
I knew that if I could get the thing out of the door that I would have a chance to get a look inside the motor and perhaps clear the problem? Or was it the door switch module? I did not know which was at fault. Or could it be wiring, or something more obscure? The other three windows worked fine but with the drivers window I could hear the faintest of clicks AFTER the click of my punching the switch. What that the circuit breaker in the switch module? Was the switch ok? I still didn't know.
"Probably need to cut the cable or drill holes in the door" said Dave after I described the dilemma.
I then visited my local Ford dealer and got a list of the parts I might need and their costs.
- The entire regulator assembly with a motor WLRA-167 C$180
- The motor WLM-267 C$55 (plus a C$45 "core" if I didn't bring the old one back)
- The switch control unit SW-7319 C$96
From the web, I learned that the motor WRM-267 seems to cost list about US$69 (Motorcraft Ford brand, amazon.com) My local ford dealers equivalent price is about US$42.50. One YouTube video advises you can get one at a junkyard for US$30. I don't know if I would go to all this trouble to analyze the problem and then replace with a used unit? Also, you won't just walk up to a donor car at the wrecker's and pull this out in 5 minutes. See the rest of my description.this one. My pictures and video will help you get the right part. Note the big grommet on the wire (mine has no wire) and the drive output is a square rather than the gear on mine. Also, they call this a "right" motor but to me this is a drivers or left. But I am in North America. So buyer beware.
While at the dealer, I asked for some specific advice about the window stuck at the top. The parts man went to talk with one of the mechanics and yes, I had to get the window out to get the regulator free. It's as simple as that. There is no cable kit so don't cut the cable! You don't have to drill holes. What you need to do is to pry the window outward while lifting it up, the mechanic told me through the parts guy.
Back home, I had the regulator loose so the window was down maybe 1" and I tried prying it outward. I didn't pull too hard because I didn't want to break anything. Not yet understanding the window retaining clips, I didn't want to break them. The clips and the cables were part of the whole assembly I would have to buy if I broke something. The clips weren't available separately. It would be helpful if a glass guy could show how this is done.
So I decided to try another route for a bit. Sometimes you need alternative approaches.
I was not sure if perhaps the switch was at fault so I decided to attempt running the motor with a power supply. I cut the two wires from the harness to the motor plug. They were too short anyway. I found this when I tried to disconnect the motor connector with the motor still in the door. The wire leads were only long enough for me to get the connector off, no longer.
On a small table, I set up a variable bench power supply and ran a line cord out from the garage. I had two test leads and two alligator clips. I attached the power supply to the bare motor leads, the motor sprang to life and the glass started moving down! I was able to run the motor! It went down without any problem. I pulled the leads off the power supply and reversed the plugs. The glass would not go up unless I put my palm on the glass and "helped" it with an upward push. The mottor sounded like it was working very hard to raise the glass. Down once again, but not up unless pushed.
I parked the glass in the recommended half way down position and I was finally able to open the clips which hold the window glass. After opening one clip and then the other, the glass lifted out of the door. Then I was able, with a bit of wiggling, to extract the regulator assembly from the door.
