    Hello, I have a 91 western unimount on a 91 GMC 3/4. My problem is that the plow will just stop working. If I jumper the two main solenoid terminals I can hear the plow motor run and the plow will work again for a very short time. I have already replaced the solenoid and it worked good for about 2 weeks. The solenoid that I used is a official western part bought directly from the dealer for my plow. If anyone can give me some advice I'd greatly appreciate it.

    Check your other connections at the battery, but I too have had a brand new solenoid crap the bed on me....within the same storm. I replaced it with the newer style round base (not sure if the style really matters) and never had an issue with it again.

    Don't over tighten the studs either, if you do and one comes loose within the base...counter productive to say the least.

    Thank you for the advice, I will be sure not to over tighten the new solenoid I just bought. I'm going to keep my fingers crossed and just hope it was a faulty piece of Chinese manufactured junk. As I'm sure you can understand I'm just worried that there is an underlying problem causing this.

    Oh I hear ya, but you would be realistically seeing other complications if there were an issue....Erratic plow operation, blown fuses, nonfunctional headlights....controller. I think your good to go if this is the only issue your getting. Obviously make sure there is no chance for the positive posts to be grounding out on something....but other then that, I think your main issue is a faulty component.

    If I were to only take one backup part with me plowing.....it would be the realy (Solenoid).

    You can also check for corroded/loose connecters, make sure the power and ground are connected to the battery and run a amp draw test on the motor.,

    I tried a new solenoid last night and I still have nothing. I did make sure that the plow ground was hooked to the battery and the positive was hooked to the solenoid. I'm thinking that I may have a ground issue now. The manual states that the joystick is grounded through the control cables. Does anyone know if there is an actual ground cable in the joystick that hooks to my control cables? I have not had an opportunity yet to tear into it. As with most older plow trucks I have an issue with corrosion under the truck and I think this is probably making some ground issues for me. Thanks a lot for your time and advice.
