93 suburban wiper motor
Any tips on how to replace this, they worked last night it snowed throughout the night went to turn them on and they tried to work and then worked on high for about 10 swipes niow they they just bump when the switch is hit. The motor is hot so I dont think it is the switch.
this happened to me a couple months ago. try pouring some hot water down the grate in front of the windshield. It doesn't have to be boiling or anything just decently warm. It worked for me.
It was the motor it smelled burnt.. It is a fairly easy job. You need to remove the wipers by pulling them up like you are going to change the blades there is a small tab where the wipers slide down on the shaft, pull it out and wiggle the wpier assembly off. Next unbolt the cowl cover thing it is three pieces you will see the wiper moter connection to the assembly that moves the wiper try to mark this so it goes back on the same way unbolt and remove(I screwed up and didnt mark it) unplug and unbolt the wiper motor assembly(10 mm screws) you need to reuse the grommets off the old motor(at least with the one I had) and the rubber shield that goes between the wiper motor and the firwewall. Basically do it all in reverse to put it back together about a 1.5 hour job easy and about $55 in parts.
