Jump start -- could I have damaged something?

[BMillar]

1991 NSX. 10,333 mi. Just wondering... About one month ago I left the trunk lid open and drained the battery. Jump started the car from the battery terminals. I heard a loud crackling sound at one point while I was sitting in the driver's seat. Shortly after that (can't say if it was the same day or a few days later because I really don't remember now if I drove it immediately after jumping it or just ran it idle for a while) the A/C blower motor malfunctioned and now only runs on high. Also, no air blows from the center console vents, but all other vents seem to work. A few days after that I noticed that the passenger door window does not operate. Are these coincidences because the car is old, or could I have damaged something and/or blown fuses? If so, what? Thanks for any help.

Well - that's certainly NOT the jump starting procedure spelled out in the owner's manual. I'd be worried - pray first and then start with the fuses.

Probably coincidence. The AC vent blowing only on high is a common problem with old NSXs (do a search), and I'd be willing to bet the window is just random (bad) luck.

BTW: the NSX has jump points on the engine bay, making jumping it much easier. It's covered in your owners manual. It took me over two years to notice this (who reads the manual for jump start instructions?), and then only because somebody mentioned it in the "NSX Secrets" thread...

Who reads the owner's manual for jumpstart instructions?

People who have seen ( or even worse experienced ) the damage caused by incorrect jumpstarting!!! I've seen some of the really tweaky European stuff really go around the bend when " Good Samaritans " helped out.

Yes, total coincidence. The window regulators on the '91-93 NSX can break at any time. Look in the FAQ for more information. This is one of the most common problems on the early cars, and has been frequently reported here over and over. (It's almost always included in things to check when evaluating early cars, and you can find it listed in the Used Car Checklist in the FAQ.) You can install the $16 window fix-it thingies to prevent the failure, but once it happens, you are likely to need to spend $500 to replace the window regulator. I suggest you get the fix-it thingie installed on the driver side to avoid the same thing there.

Just a side note, if you have a BBSC you can't even jump it off from the engine compartment. Because the fuse/relay box is buried almost upside near the bottom of the compartment.

I was asked in private for more information about the fix-it thingies. The problem is well described, including great photos, in the FAQ (look it up under Troubleshooting - Power Windows), and you can get the fix-it thingies from Science of Speed or Dali Racing.

i did this the other day and was very easy. Keep in mind, that this was my first in life. No worry, just do it Now it is time to pull your manual out.

While it's a good idea to check for the "window fix it thingies", when they fail the window goes thunk and disappears into the door. You heart stops and you wallet gets lighter by about $500 ($300ish with NSX club discount). I know first hand...

"Window not working" is usually the window off switch on the driver's side.

 

[nsxtasy]

A few days after that I noticed that the passenger door window does not operate.

Is it possible that the lock button on the driver's side somehow got switched?

(I know that this is pretty obvious, but it never hurts to ask...)

Well this thread has been informative, I did not know about the jump points in the engine bay, and will keep that in mind for future reference. Its not the window regulators (already changed those) and its not the window switch. I have examined the fuses, and I cant obvously tell/see any bad fuses. I am guessing that it might be just a bad switch? The electric window switches have gone bad at random intervals in several other vehicles I have owned.... As for the AC, I have no idea, maybe also a coincidence

Anyway, I should know something definite within a few days as the car has been dropped off at Acura Carland in Duluth for these issues and to have the T-Belt done, as the car is a 91 and has never had a belt change.
