Might try changing the fuel filter also, just to rule that out.

Those wheels look great on the car! Fellow quest & C5 owner here as well

You can get enough current to weld out of a 12V lead acid battery, which is more dangerous than a current-limited power supply if there might be a short in the wiring you're testing. That being said...I still just use a battery. Good luck.

Cool! That's a great idea. Thanks for posting it.

All my A/C experience is with R134a, but 0psi on the low side with the compressor running says to me that the system is low on refrigerant.

Turbo Cary's advice above is great. Also, given all the problems you mentioned, I can't help but wonder if you have a problem with your ETACS module. I'd start troubleshooting there.

Damn! When I got my parts from SendCutSend that I'd prototyped with 3D prints, the dimensions were dead on. Makes me think you might have a dimensional accuracy issue with your printer that got baked into your design. Looks like the important parts are close enough, though. I'm sure you can make it work.

Really? Do you have a picture of that? My rear wiper arm works exactly like the fronts. The pin is not part of the arm.

Yes, the new blade will probably come with half a dozen different adapters, one of which should accommodate the removable 3/16" pin. It's pretty hard to find wipers with built-in pins like that anymore. I'm not aware of any.

I have one that worked when I pulled it off my car. What's it worth? $35?

You'll need a separate pin. The part is ANCO 48-05 (or 4805) but they are hard to come by.

Thanks again for all the great info here, @kev. I got my parts; all the fasteners I pulled are in individual labeled ziploc bags, and the ones that the previous owner had already pulled before I got there are all mixed together in another bag. I seem to have everything, at least I haven't found anything that I'm missing yet. The square plastic inserts for the A-pillar trim are really hard to remove without damaging them! I managed to get one of the four out cleanly, the rest I broke, or were already broken. The white plastic inserts for the seatbelt mechanism in the door were tough too; I got one of those out intact, and figured that was good enough. Since I have one good example of each, I can 3D print replacements for both of them. I tried to pull the belts out of the reels to inspect the webbing, but it seems like they're stuck. Is there a trick, or is something broken?

0.8mm is the most common thread pitch for M5. Since Mitsubishi generally uses finer threads, that'd be my bet.

Nice! Yeah, spa turbo stuff is good quality. Glad they're still making these.
