If the drain hose is not clogged, the leaking roof may be due to the frame on the sunroof rusting and a rubber gasket leak. I fixed the leak on ours by cleaning the gasket and top glass and sealed the top of the sunroof gasket to the window with a silicone caulk. For the past two years it has not le...

The 850 transmission mode switch (winter, economy, sport mode) is gummed up. I removed it and cleaned it best I could without taking it apart, but the winter button does not seem to move freely. Looking at replacement parts, the original number on the switch in the car now is 3515004, but according ...

Good idea, instead of just replacing the MAF sensor like the mechanic is suggesting. I'll try that today and will read the codes before and after and post back.

Thanks.

When the car does act up, the car idles steady when the shifter is put in "neutral" or in "park", but stalls out when put into gear.

And when cold, most of the times it idles steady when in gear.

Update: I took the winter sport economy switch out and cleaned it up best I could. It seems to work as far as I can test it..higher shift point in the sport mode, but the car still has a problem. The local shop replaced one rear caliper (less than $100.00 to do it - dealer wanted $670 to do both rea...

That would be my story..intermittent car stalling and car shutting off when slowing down at times but when immediately put in neutral or park the car idles fine. Try to put into gear and it sometimes dies. The car is at the local shop now and I will not know anything until Thursday at the earliest. ...

Thanks..I will sure take a look into these possibilities. Hopefully it will not be too expensive of a repair. But I am puzzled as to why the CEL is not on or why there were no other codes in A1 of the OBD?

Thanks for the suggestions...I took it in to the Volvo dealer at my wife's strong suggestion (*I think she does not trust my mechanical ability*) ...and they could not duplicate the problem, but during the inspection, they stated that the rear calipers are seized or not working right. Since I recent...

The problem started just recently on the wagon (236,500 miles on it) where at times when slowing down the car starts shaking and runs real rough, but when put it in neutral the shaking stops. My son usually drives the car and he said that this does not happen all the time either. I took the car out ...

On our 1994 850, the switches just popped out without removing any trim, but I am not sure about a 1997 vehicle. Just a small fine bladed screw driver or pick to gently pry up on the side and top of the switch. The switch then pulls our and disconnect the plug. The bulbs are very easy to replace and...
