SOURCE: When should a timing belt be replaced on a 2005

the recommended replacement is at 105,000 miles

SOURCE: '06 Volvo V50 drivers seat belt is jammed.

I solved this on my 95 volvo 850 glt as follows:

pull the seatbelt pilar cover off from the door jamb. this runs vertically up the pilar between the front an back door (beside the front seats. Once opened loosen the belt by gently pulling the belt upward toward the roof. You'll have to do this sometimes in small increments. Once the seatbelt is pulled out all the way, spray small amount of lubricant into the joint where at the top of the belt spool. Also use a screw driver to push spool upward while pulling the belt. At first it's only going to release a little but eventually the lubricant will work its way into the seam at the top of the belt spool and loosen up the stuck inertia catch. Until it completely loosens you might have to remove the pilar cover again and work the seatbelt out (also use the screw driver technique described above) in order to use the seatbelt. When parking, I would relatch the seatbelt and pull the slack up around the back of the head rest. After a day or so it worked normally.

good luck and don't give up.

Testimonial: "Thanks, this works! Got to mechanism by taking small hole edge trim off, pushing it upwards released ratchet. No probs since. "

SOURCE: My 2006 Volvo V50 won't start.

Check the passenger foot area. The CEM is located there and many time passengers unplug connections with their feet unknowingly.

There is only thin insulation between the foot area and the CEM.

CEM= Central electronics module.

I have been having this same issue for the past 6 months. So far no one can give me an answer that solves the problem. I have done several things unsuccessfully 1) changed the battery (still happens) 2) flipped the valet toggle switch under the steering column (still happens) 3) I lock the doors using the automatic lock button on the driver and/or passenger door (the alarm will not self-activate and go off, but this still doesn't solve the root problem with the alarm)
