Problem is:some times when i turn them on, they dont start. So then i have to grab a wiper and force it to move and then they start moving.Also some times they will just stop working, and i have pull on them and move them to get them started again.The motor is strong and will work on all the speeds.And the wiper switch in the turn signal arm feels good and seems to be working.Could it be a bad rely or a dead spot on the wiper motor ?thanks
Most likely a bad wiper motor. You could test this by tapping on the wiper motor when they stop working. Use the handle of a big screwdriver and give the motor a good tap. If the wipers start working I would replace the motor as the brushes in the motor are worn. Motor is usually located up against the firewall somewhere and about the size of a soda can and black.
Sounds more like lack of lubrication coupled with dirt and dust in the motor and mechanism linkage. Use some WD-40 and spray and lubricate all the moving parts.
i ad a similar problem with a truck of mine. it may be dust buuilt up inside the switch. i had to ever so often turnthem on and off real fast to clear it out. seems the would work for a while after that. also check where the wiring harness plugs into the wiper moter, have had some trouble there to. as far as it bein the moiter it is possible but it will work every now and then so it kinda points else where.
