I HAVE A 1995 850 GLT WAGON THAT I HAVE CHANGED STARTER MOTOR, IGNITION COIL,PLUGS ,CAP, ROTOR , ENGINE OIL AND IGNITION WIRES. SOMETIMES CAR STARTS RIGHT UP. WHEN I SHIFT TO DRIVE ARROW STARTS TO FLASH. I STOP, PUT IT IN PARK WAIT FOR CAR TO WARM UP MORE AND NO ARROW FLASH. OTHER TIMES IT DOES NOT CRANK. I HAVE BATTERY, HEADLIGHTS RADIO. I TURN THE KEY TO II ACCESSORY POSITION PUT MY FOOT ON THE BRAKE AND SHIFT TO THE NEUTRAL POSITION THEN CAR TURNS OVER TO START. THIS IS AN AUTOMATIC. I CHECKED CODES UNDER HOOD. NO ERRORS 1-1-1. IS THIS A PNP SWITCH PROBLEM. MICRO GEAR SWITCH PROBLEM. NOT SURE ANYMORE. I TRIED THE RACHETING OF GEAR SHIFT BACK AND FORTH. DIDN'T WORK EITHER. THIS ALL STARTED WITH COLD WEATHER. I USED A ACTRON OBD TESTER AND GOT A CODE OF P0705 CLEARED CODE CAR STARTED ONE DAY RUNNING OUT OF WAYS TO START CAR. NOT SURE WHAT THE PROBLEM IS.

I would have said PNP switch with the symptoms you write about but no codes- this is very odd indeed...still think PNP.

Btw, typing all capitals is the same as screaming on forums.

Sorry about the capitals there. I am new to this post. Appreciate the input.
I'm ordering a neutral safety switch and will I guess see what happens from there. I've just about run out of solutions to what it could be. Ive wander all over sites and it seems PNP switch (neutral safety switch) . Still would like input if you think of something it could be.

The arrow on the dash, the having to start in neutral...all point to that switch. I'd say it's too far gone for the ratcheting to have had any effect. Still can't figure out why you don't get any codes for it.

Actually, when I looked up the code you posted- P0705. It stands for Transmission Range Sensor Circuit malfunction (PRNDL Input). When I went further and looked this up on other forums, everyone just talks about the PNP, so I'd say that it is a very good bet that this is the code for it.

I've been to past topics searching all day. Went to brickboard, volvo speed all over the internet. I know its not the transmisson at all. Once the car is started and driven a while no problems. About 1 hour drive to work . Doesn't hesitate, runs great no problems. I do know that if I drive and make a not long after starting out for the ride to work if I turn the car off it won't start again so I leave car running grab coffee and off to work. Sorry for all the details just thought it might spark a suggestion. The car will give no problems after I get to work. I can start it later with no problem. Then after it's cooled done after eight 1/2 hours of work I start all over agian hoping it starts again. I also notice. that when I do get it started when I shift from park to drive while taking it out of drive the arrow flashed for a moment (wintermode) on instrument panel. I don't think that would have to much to do with the starting problem thou. It just does not turn over. Although I have to play with the gear shift now. Which leads me back to PNP which can put a car in limp mode from what I've read on forum posts. I'm completely baffled.... Once car has been running no problems with shifting, lights or anything.... It's like no problem exists. Just on cold starts...

It is baffling. I'm typing on my laptop now because my desktop computer decided not to boot up into normal or safe mode and I'm having to reinstall WinXP again (second time in a week). Also, my car decided to stall out on me today too....very strange things are going on. If I figure this out I'll post, but still I think the PNP switch in your case....I'm hoping a weak battery and/or dirty air filter in my case.

I agree with MIJ, sometimes you just don't get codes. Here is a site for PNP switch repair. http://www.volvospeed.com/Repair/pnpswitch.php
Here is a thead also.
http://www.volvoclub.org.uk/forum/showt ... pnp+switch. After reading this thread , do a search and it has numerous mentionings of PNP, with similiar symptoms as yours.

Thank you for the advice I ordered a PNP Switch from FCP Groton and a selector switch, I thought I should put in original Volvo part instead so the price was not too bad for original Volvo brand. I figured I didn't need any other problems if this was the cause.

I read on other post that I could have purchased from AutoZone for the PNP switch Wells brand and it worked for others. It was 49.99 and has to be special ordered. Just in case someone has this problem and didn't want to go for the original Volvo part. Half the price of original.

Does anyone know how to remove the mode selector switch. (Winter, Economy, Sport) I thought I would remove and clean it out if it might throw a signal to the transission also.) I know also when the arrow comes that would throw the car in Winter mode. When it flashes its an error in the automatic gear box.

I seem to have no luck now though. My 1987 Volvo GLE is in the shop prior to this . In for the External fuel pump. In case someone needs to know theres 2 on this vehicle. Internal and External. Internal in gas tank. At least its not the internal one. It's a work horse of a car. 230,000 miles. Manuel . I love it.

I thought I would let everyone know the status of what exactly was the outcome of the volvo 850 glt 1995 wagon.
Ok - three starters later. The starter was bad. One after the other.
I put in a new PNP switch from the start because I had no reverse lights . The arrow would also flash on cold start ups in the morining and do the limp mode thing. ( Almost not drive at all) thats when I could get it turned over. No codes on the diagnostic under the hood either. Also had a new battery put in. Good idea when you've gone through 3 starters. Finally picked up my car after switching starter after starter. So my car now starts right up in the morinings on cold starts and all. Runs perfect. No longer have to wait for the long warm ups in the morning and no problems. .... Whatso ever.... So what was the outcome.
PNP switch for reverse light.... Starter for the dead starts in the morning at times. All I know is it works now.... Hope this helps someone out there. It was a frustrating 2 weeks only beacause when the 1st starter was installed. The mechanic was at one location got the car to work and it was at another mechanics location. So it was more of the taking the starter out switching off and bringing it back between mechanics. It had a warranty so that was what I had to do....
I just wanted to let you know. Thats for all the help.... Sometimes post forget to come back and tell us what the solution was to some of the problems posted.... Till next time...

Yes, thanks for coming back and posting your end result(s).
So it was the PNP as well as a bad starter.
Strange things start happening to these car's electricals when it gets cold.
