2nd Gen Non-Engine/Transmission Power seat motors - revisited

[BigPapa]

I searched and found several threads on power seat motors talking about bypassing the built in "circuit breaker" in the motors but none had pics.



Is this red component what they're referring to?

I have no continuity from one side of it to the other. Could I cut the wire, solder it together and put a fuse in line of the wires going to the connector?



Thanks.

Before you do anything rash (and possibly fry some electrical systems) check out my post https://www.turbodieselregister.com...ons/230179-98-02-replacement-seat-motors.html



I too had seat motor issues and tried almost everything until I hit a post mentioing "two guys one garage" and seat motors. Now, after almost 5 years with only one motor (front up/down) working, I once again have a fully 6-way adjustable seat.



Good folks at two guys one garage.

Thanks Joe. I saw your post. Good info.



I would like to look into fixing what I have, though, instead of spending $200. I have obviously taken the motor apart and everything looks good, nothing burnt or broken, so I'm confident there is something that can be repaired. I'm just not familiar enough with the internal workings of an electric motor that will turn in both directions. I've replaced brushes and resurfaced armatures on motorcycle starter motors, but they only turn one direction and don't have these "extra parts".



I'm confident I'm not going to mess anything up and I've got nothing to lose, they're not working now. I tried removing the "component" and soldered the wires together. Still doesn't work. I'm trying to do a little research on the workings of this type of motor. If I come up with anything I'll post it here.

I'm not sure but that thing in the picture looks like from the markings to be a resistor. If you have an ohm meter it should read 224,000 ohms. Its purpose is to block any voltage spike from the motor winding getting back into the vehicle wiring. If the motor has permanent magnets for field coils then that may not be what it is. If there is a thermal cut out it will probably be a short bi-metal strip with contacts on one end that open when the strip heats up. The motor reverses directions when you reverse the polarity to it. The rotor could be bad, you chould be able to read continuity through the segments opposit each other that the brushes contact. There should be no continuity between any segments and the shaft. Hope this helps, I've already told you more than I know. bg

Big I hope you can get them going. I know I tried and was only able to get the old ones going for a few days then they went out again. I went years without them so I felt the old "butt" deserved a bit of comfort and whet for it.

224k250 is a family of capacitors. I would expect this one to be fitted across the carbon brushes to minimize interference with other electrical circuits, including the radio. The interference comes from the slight arcing at the brushes. Here is a link to a source for the capacitors: 224k250 Availability & Rapid Quote Request

thinking about putting my 95 seats with power drivers in my 02 ram,,,,that built in breaker just may ,make it easier
