flashing arrow / blinking econ/sport lights, PNP switch? 850

Hello list,


here is my problem, i was pulling into a parking space and when i shifted to park i noticed the yellow arrow strarting flashing, when i looked at the winter mode switch (i thought maybe i pushed it when shifting to park) the sport and econ lights were blinking alternately one then the other. I switched the winter mode and the all the lights were still flashing, i turned off the car and restarted it, all lights still flashed. i shifed to reverse aned moved to another parking space, when i did this the car was in first gear not winter mode, drove around lot, parked car, shut it off, back on lights still flashing. Now did i mention this was at the airport and i needed to catch a flight, i will be back tomorrow to get my car and wanted some info.

The temp was about 40 degrees, i thought i heard the PNP switches fail when it is cold, is this right?

I do have a code scanner, but have not pulled the codes.
Does this sound like the infamous PNP switch?

I am in the process of searching the forumns, but wanted to post this message also.

Thanks for the help.

    When you get back, try to clean the contacts on the PNP switch by moving the gear selector from Park to 1st gear 20-25 times. This will probably help temporarily but you'll eventually need to change the PNP switch.

    It could be the PNP (most likely suspect), but other problems can happen with the tranny. Pull the codes to be more certain. Socket A-1, code 3-1-3 is a near-certain PNP problem. Also code 3-2-2 can show up. Any other codes, and you might have other issues like solenoids, etc.
