So after driving my new '87 760T (wagon) for a few days I noticed that I didn't have any washer fluid going to my front or my rear windows.

I found power at both pumps and disconnected the hoses from the pumps (the ones that go to the nozzles) and watched for any fluid getting pumped out right at the pumps - nothing!

both pumps klunk when the switch is turned on (I'm assuming they are supposed to whirr??) so I'm wondering... could both pumps fail the same way? or am I missing something?

also I noticed that FCP Groton has a higher price on the rear pump than the front pump but after checking them both pumps look like the exact same part???

if I bought two front pumps and put one in place to work on the rear window would I be screwing something up ???

thanks,

jack

p.s. - yes there is fluid in the reservoir, it spills out every time the pump is removed... maybe the inlet to the pumps are both clogged???

I had pretty good luck unscrewing the bottom plates to get at the impellers. Caked minerals and wiper washer gunk can br removed and the pump might work fine.

Try cleaning their grounds. On my '87 760T's (sedan) front washer pump, it had it's ground going to a point somewhere on the inner fender next to it. It started working after cleaning its ground.

My experience is that they bind up internally with crud. If I was at home at my desktop rather than onthe road with my laptop I could include a writeup on the procedure to fix your existing pumps. It is pretty straight forward- take them apart and clean them up, lube the moving parts with synthetic grease and put them back together.

Randy, when you get back kindly write this up and send it in for the FAQ.

If I can repair them I will...

I'll try taking one apart and see what I can do with your suggestions, hopefully the details will become apparent.

did the ones you repaired "klunk" or did you just pull them and repair them?

thanks Randy, I'm having hope!

I just run them in reverse for a minute when they get stuck and then they are fine for a long time.

I tried this for about 20 seconds or so and nothing but klunk both directions...

should they make a whirring sound and feel or have your clogged ones failed and just klunked????
