Location of windshield washer pump

[Mister-B]

My pump is bad. Looks like it goes under the dash, but does anyone know exactly where? My local junk yard has two of these trucks, so I want to see if I can find this part under the dash, but don't know where to look, or if it is hard to remove?

It's attached to the wiper motor which is to the upper right on the inner cowl behind the instrument cluster. It's harder to access if you have A/C. Easiest to get at if you pull the cluster.

All you need is long arms, flexibility, time and patience.

Here/s a couple of pics of the pump.

Thanks for the additional info, guys. That helps

Ok guys. I got it out of the junker and bought it. It was 6 bucks, is off a 71, and looks brand new. As an FYI, removing the instrument cluster doesn't help. I did that, since it was a junker, but it didn't help. It's actually closer to the radio. One junker had a radio, and I had a hard time getting it out and gave up. Went to another junker that had the radio removed, and it was cake to get to it

Here's another option you might want to consider:

I took the tank with the electric pump from an S-10. I wired it into my washer switch so it works with the center button, but it's easy to get to, has great pressure, and I can replace the whole thing for less than $10 and about 5 minutes of work if I need to.

I mounted it in the same location as the stock pump.

Truckster, thanks for the tip. I've owned my 71 going on 2 years, have tried to replace the mechanical pump twice now, and still can't get it to work. I'm gonna try your fix!

[Malamute]

Make sure it's not the lines that are plugged. Mine sat outside at the previous owners house and they were plugged when I bought it. I'd hate to see you pull things if you don't have to.

Same location as the stock washer reservoir, right? Not pump... ?

Great tip btw.

[truckster]

Yeah, sorry. I meant the reservoir. The pump on the S-10 washer bottle is on the bottom of the bottle.

I also wired the switch using spade connectors so I can go back to stock if I want to.

Glad it was "cake" for you. On my truck, with the radio out (actually, the back of the radio cut off...but that's another story), AND the instrument cluster/bezel out, steering wheel off, etc. It was a PIA.
I was a 66 year old pretzel under the dash (bucket seats IN, unfortunately).

So...I didn't wanna do it again. I left the broken pump on, IIRC, and put a $16 electric pump on top of it, replaced the hoses because I wanted to, hooked up the electrics from stock to the stuff supplied
in the Napa kit.....tested it for leaks. Tested it again. Closed it up. It's not stock. But some things are simply better than stock.

Unless someone with a clip board is climbing around under my dash (Hardy-har-har), I'd rather have it work than have it factory.

Of course, YMMV...As it should with all of us.

Here's the rez. Ran the ww supply hose behind the fender.

never had any luck repairing the factory windshield pump, they just don't seem to hold up for very long, i always just add one under the hood and fix the problem....works good for me.

Oh great. That hassle, and it might not even work or hold up...

Never had luck with used pumps. This last round, I bought a new one from Classic in Mo. Works great and has that wonderful "Clack" sound when she's a pumpin. Did I mention, I love my ole truck....

[eagleuh1]

I bought one at O'Reillys. looks just like the original. Its just the pump part inside the cab. Think it was like $13.

[bignbad]

I rebuilt my pump works like new but it was a pain to get too that was like 7 yrs ago and still going strong.

[dirtwork]

Which generation s10 did you get the bottle from? 80's 90's? or does it not matter because they are all the same?

[truckster]

I think it was a 90s, but I'm not 100% sure. I was looking more at the condition of the washer bottle. I think either would work.

I can take pics tomorrow if that will help.

Yes please post some pics! I am interested as well.

the one from LMC is about $28.00 it works good, just need to beef up the bracket a little.
