Cleaning Windshield Wiper Motor

BDD · 05-18-2008

My windshield wipers move slowly. I'm assuming that the lube on the wiper motor may be dirty and causing drag. How would I correct this?

You can remove the motor and the linkage and do a bench test to see how things are operating. It may be that the grease around the linkage connections has hardened and are slowing things down. The easy way is to clean off what old grease you can and then to add some oil or fresh grease to free things up a bit.

Thanks. Didn't know if I had to do more than that.

Curious if everyone is happy with the GT windshield wipers. I have been considering using an aftermarket motor and linkage.

Are you guys still using the 30amp alternator? I switched to a 65 amp but have not yet fired it up. So I wonder if more juice might be the answer......

If the mechanical linkages are free then it could be gummed up bearings in the motor or the copper wires going to the communtator bars break and the motor losses torque but still runs.

Would you consider your wipers to be sufficent for heavy rainfall when the motor and the linkage is properly cleaned and greased ?

Not according to todays standards would I consider my wipers adequate. That is why it has been recommended to use RainX or equivalent on the windshield if you are going to drive in the rain.

I like RainX. I used it on my truck after the wipers went out and it worked great. Don't really need the wipers with the RainX.

On the 1970 GT that I used to have in the 70's and 80's I thought the windshield wipers worked fine. I just saw a video on You Tube that might have been from an old commercial. They were driving GT's in the rain on a test track I think and the windshield wipers were moving pretty fast, mush faster than mine do now. I'm pretty sure though that the high setting is faster now on modern cars than it used to be.
