Windshield wiper motor remove and replace

**BigT67** · #1 August 21st, 2009, 02:13 AM

A common issue with tenth gen f150’s is for the windshield wiper transmission to come apart like so:

To remove and replace this assembly, start with the wipers. Pry off the caps over the wiper arm nuts. Once you have the caps off, a 15mm socket will remove the nuts. A couple of taps with a light hammer will break the wiper arms loose from the splines. There are 7 or 8 philips head screws across the top of the cowl. (you may want to remove the radio antenna for easier access to the screws on the passenger side.) Once those are removed, open the hood and remove the clips.

Next grab one end of the rubber weather strip and pull up and across to remove this. Now you should be able to remove both halves of the cowl. Once the cowl is out of the way, unplug the wiper motor and remove the three 8mm bolts. Next comes the tricky part. Working from the drivers side, push the assembly towards the passenger side and work it into the well area below the transmission assembly. Now pull back towards the drivers side until the far end drops into the well. Work back and twist the wiper motor towards the front of the truck, while lifting up on the end nearest you and carefully work the assembly out of the well area.

After you have removed the assembly, you can turn over and remove the four bolts (8mm) and separate the motor from the transmission assembly. Bolt the wiper motor to the new wiper transmission assembly and re-assemble in reverse order from above.

Now, I tried to ‘fix’ the joint by stuffing a grease covered piece of sock in between the plastic cap and ball joint, but it came apart after half a swipe.

This assembly is not available as an after-market part (yet) and buying it from the stealership will cost you around $125 (without the wiper motor). If you decide to go the wrecking yard route, make sure you check for play or release on the replacement part. Obviously this procedure is the same for wiper motor replacement.

Add a little of that Rain-X or whatever they call it and yoU don't have to go as fast!
Or tie some rope to each side of the wipers and rUn it throUgh each side window - then pUll one way then the other!

I broke down and bought the new assembly from the Ford parts counter and did the whole remove and re-assemble again (Grrrr) and now the effin wipers are backwards! They stop in the up position. Somehow during the re-assembly the motor got out of sync and I just haven't had the time to take it apart a third time (kitchen plumbing decided to come apart and ruined the floor of the cabinet). Plus the salmon are beginning to show up in area rivers!
