Thought I'd do an update. It's been .. interesting.My spare came yesterday. I think I'll put the spare and the stubby screwdriver in a nice padded box and fasten it someplace in the "trunk" area. I figure if I actually have an alternative there, I'll never need it ..
On the other hand, just saying that out loud probably means it will happen and my spare will be defective.
The cheap part I bought died about a month later. (it started getting flakey, sometimes it would work, but then it would stop unless you kicked in the air conditioning, then it would work again for awhile)
I'd thought I was being smart, so I had ordered a second to have as a spare, and then a week or two later decided to order yet another one - a more expensive one - as a spare since I KNEW that part was the issue.
So, I put the "more expensive" one in. It didn't work at all, it was dead completely. (A Dorman - I bought it on Amazon "warehouse discount" which in retrospect was stupid since you know Amazon just looked at the previous return, said "looks fine to me" and put it back out for sale)
So I put the cheap second spare in. It worked ok, but constantly threw a check engine light that I couldn't get rid of. It would come back on each restart. So, since it worked beyond that, I ordered a FOURTH part, meanwhile prepping my Amazon return to go back to them.
A few days later, the new cheap part arrived, it works flawlessly. I figured I'll keep both flakey ones as spares and if I get one more failure, I'll buy the AC Delco one.
The lesson? Yea. If I'd bought the AC/Delco one in the first place, it would have been fixed the first time. On the other hand, I would have forever after bemoaned the fact that I paid $140 for a part I could have gotten for $25. Humans are so hard to please.
