Years late to this poll, but for the sake of others who might be looking for answers here, I found mine to be, oddly enough, the engine coolant temperature sensor (ECT). Sensor itself perhaps, but more likely, the electrical connection to the sensor. These go bad over time and cause strange engine s...

You can find a link to sign up for email updates at the blog main page, on the right column below the topic index. At the very bottom of that column is a field to enter your email address to follow the blog via email. My college girls like the car well enough because it's safe and reliable and comfo...

I would be happy for you to link my blog on any other site that involves Volvos or general car repair. I hope it is useful even in Scandinavia.

Yes, I am a member of this forum and I get a lot (maybe most) of my info from MVS! Thanks for the mention; I hope others find it useful. I have been making the blog more informative over time. It started as a way for me to share this info with my kids so they appreciate how much cost and effort goes...

Hi Dave, Sorry, didn't mean to confuse you on this. I was specifically addressing this post topic of jmmxc's 1996 model 850 as he reported problems with both the speedometer and ABS module. I can't offer meaningful advice on your 1989 model 740 as they are likely different and I haven't looked into ...

An excellent writeup on ignition switch replacement found here: www.matthewsvolvosite.com/forums/viewtopic.php?f=1&t=37398 IPD also has a good replacement procedure for that part number. Download from their part detail page (OEM 9447803). You can buy a replacement switch in the $55-60 range from...

One other thing to check is your ignition switch. I have a '97 model 850 with a flaky intermittent ignition switch which causes various symptoms (no speedo, can't shift out of park, ABS light, no headlights or turn signals). Wiggling the key makes all these go away and the speedometer starts working...

Well, it took a few months to get around to this but I figured it out myself. There are two gas springs in the rear of the seat which push the lower seat assembly apart from the upper seat assembly. These gas springs weaken (lose pneumatic pressure) with time and use to the point that they don't pro...

Anybody know of a common problem/fix for the inability to adjust manual seat height? Picked up a "new" 1997 850 NA wagon with manual seats for my daughters in college. Other seat adjustments work fine but I can't raise or lower either front seat using the lever on the side. Lever moves for...

Question to Ozark Lee: That photo you posted earlier showing the keyless receiver black box to the right inside the glove box, is there an alternate location for it? I'm trying to locate my receiver in my 1997 model 850 and there is a big blank space there. Can't locate the box but I know I have one...
