Current situation:ee652140ba15fb00ca87ce92058fffc9.jpgfaa5e441bb77fbe9612eea4df4f31320.jpgi bought the replacement pump, since that seems to be the weak link. But as soon as I opened it up, I see the lines are trash. Now I don’t know what goes where. Lol. Any tips appreciated. I guess I’ve got a 50/50 shot. ecde75c33258e8aa00b617166fc8a794.jpg
Ok. Got the right lines attached. Yay. On a pissed the **** off note, the pump I ordered from a GM dealer was the wrong damn one. So didn’t end up replacing it after all. Sonsofbitches! e36a3ab530b3c648402675f60ff078ce.jpgi also managed to break the plastic clip that holds the washer fluid level sensor on, so for now a hack job o-ring was the best I could do. It’s pretty tight in there anyway, but don’t feel like going to get a replacement, and wiring in a new one today. It should hold for a while at least. 10d704317421892fadf67c0e0a54e7d4.jpgreplaced the rubber connecting tubes as well and clamped them just because. 5da785b0fb8be82c2f4a7ad06075ad0c.jpgannd.. since watching @Fosscore, I had to touch up the terrible looking battery tray with some fresh black gloss. Lol. It still looks like crap, but significantly better than it was. [emoji23]3bac919c74c66a09964041596d5034a2.jpg

I did mine not too long ago but forget which is which. My rear wiper is deleted so I didn’t need that one hooked up, the hose just goes above the tank so it doesn’t leak, and there’s no rear switch so it can’t be activated. But when I put a new front line in I hooked them to the wrong pumps so when I hit the front fluid it just shot out the rear hose all over the place. My 50/50 didn’t work good even though I was so sure I had it right that I buttoned everything back up including the battery tray and battery. I suggest using a set of jumper cables to connect to the battery while it’s out so you can check the pumps. And that o ring trick looks like it will hold fine imo.

Yeah, I put the battery back in to test, and surprisingly I got it right. Lol. Now I’m just waiting for the paint on the battery tray to dry so I can put the rest back together. I also failed to notice there are 3 shorter 10mm bolts, and 4 longer ones in the tray. Silly me, assuming that all 7 were the same length! [emoji23][emoji1787]ok. Think I have them figured out. The 3 shorter bolts should go in the marked holes:

changed the picture.. I decided it was much easier to put the longer bolt in washer reservoir. [emoji106][emoji16]
