Hi Wilson,

My 945 is a turbo and removing the air box lets you get at everything.
The rear window pump is on the fender side.
It's good to have that little transfer hand pump from HF to save a tank full
of washer fluid.
When I took the connector out of the pump, one of the two lock snaps
for the housing was open and one of the pins had fallen out.
The pins were fine but the support for the pins crumbled apart.
Maybe the prior owner cleaned all of his bullet connectors with carb cleaner
or some strong solvent?
Luckily I had a pair of female bullet pigtails left over from fixing the OBD port.
I use non insulated #18-22 butt connectors and shrink wrap and put it together.
I put a little washer fluid and tested and all OK.
Then Murphy showed up. The windshield pump was leaking. Pull it out and the tank grommet was gone. Looked everywhere, called Volvo they didn't have a listing for the grommet? but did have that seal you wanted. (sorry didn't get a price,
Its better that way in case you decide to shoot the messenger)
Then I yanked the tank out. There's a handy screw cap to look in the tank, and there was the grommet in the tank, hiding.
When I wasn't looking Murphy shoved it in there. (Same old story)
12" hemostats to the rescue, put it back together, happy as a clam at high tide.

Now I plan to order a new housing and some spare female bullet connector pigtails from Dave Barton, since it seems every time I go near one, the pins are falling out. He also sells the housings with and without pigtails.
His standard gauge pigtails are just fine for the 18 gauge wire for pump, OBD port, etc.

This post is a heads up to check the pump connector before ordering a new
pump. Now I have a spare pump.

Have a great weekend, Bill
