Is my ignition switch or my pnp switch going bad, and or are both going bad? 850

posted by  someone claiming to be 777 on  Sun Oct 22 13:33 CST 2006 [RELATED]

Greetings:

I have had my tranny arrow blinking off/on for the last week or so! I would get this light every 2-5 days or so. I usually remove the fuse (15 amp)and reinsert it after a few minutes. Additionally, I would diconnect the battery for a brief moment. Upon reconnecting my battery and reinstalling the fuse the car would not start for at least 3-5 minutes later. I would fully engage the key and all I would hear is an electronic relay click within the dash board area nearest to the fuse box underneath the hood? Then moments later the car would start minus the blinking arrow light, which when in blinking mode it causes the car to move extremely slow like it is stuck in a gear and or low on tranny fluid? Today I just racked the shifter for about 20-25 times from the park-low gear because of the arrow light blinking again. Upon trying to restart this time the car wouldn't start until 3-5 minutes had passed then it turned right over! I am going to flush the entire tranny tommorow from the upper cooler line. Might old fluid be part of the pnp switch being set off. I understand that by racking the shifter, it sort of cleans the copper contacts. What say you? Thanks in advance! 1995 850 GLT Wagon A.T. 155,000 original miles.



Best Regards

    It could easily be both. I would consider replacement of the ignition switch electricals and the PNP switch to be a preventative maintenance step on any 850 at 100k or more miles if they haven't already been replaced for failure. It is only a matter of time for those switches and it is much better to replace them in the comfort of your garage on a quiet Saturday afternoon than it is to have the car towed home from a New Year's Eve party :).

    This sounds very much like a PNP switch. Not uncommon to replace at your mileage. I replaced mine about 10K ago at about 118k miles.

    If you 850 is a 1996 or 97, go get your codes read at an Autozone or Pepboys. If it 1985 or earlier, read the codes from A1, and it will tell you exactly what is wrong.
    I would suspect neither the PNP or the ignition switch from what you have said.

    Sounds like it could be both. After the car does start can you shake your ignition key and it have an effect on the car? Tranny fluid may not have anything to do with this but if you're at the miles for it to be flushed, by all means do it.

      I shall try the key senario tommorow. But this only seems to happen when I disconnect the battery and or remove the 15 amp fuse for the engine/tranny control. Might it be the computer in a reset mode status. The delay is usually no longerthan 3-5 minutes at the very least. This car seems to depend a great deal on its electronics? My 740s' (8 valve wagons non-turbos) 1988,1989, 1990 450-500,000 and 1990 with 165,000 original MILES and no issues. Despite this I think the 850 is a good model, one must just take extra care of them.



      Best Regards!
