QuestionHi-
I have a 93 850 that appears to be stuck in winter mode.
Seemed to happen in cold/wet weather,but now it is constant.
The arrow indicator on the dash flashes, along with
the LEDs on the winter mode switch. I've cleaned the connectors on the inside of the switch- they seemd ok though.
I also tried bypassing the switch- and it still remained in winter mode.
I've heard of the problem possibly being the PNP switch.
But my repair manual has no mention of it and I have no idea where/what this switch is.
Suggestions,as always appreciated.

Answersorry for late answer website was not working.it could be the pnp switch which is on top the transmission.where the shift cable attaches to the transmission shift linkage.it requires special tool to set it up properly after replacing it.you would need to check for codes in the transmission control unit below is how to do so.
behind the passengers side head light are 2 small black boxes,1 marked A ,and 1 marked B.on box A there is a small wire insert the wire into the hole marked 1 then turn the ignition key to position 2 but not started.then on the box narked A push the small button for 1 second then release it.the small red light will flash a code back as a 3 digit number.there is a short pause between flashes for a single digit and long pause between the different numbers.example:
a 121 would look like this flash.....flash..flash....flash
write down each code,then after the first code repeats its self then press the button for 5 seconds the light will light when pressing button then go out when released,then the light will light steady again when it does press button fo 5 seconds again,this should have reset the check engine light.let me know the codes. i will tell what they refer to.
