Question Hello

Hi. new member, grateful for the opportunity to learn and share, here.
Other than my trusty old Corolla or Honda wagon for daily driving, Volvo Wagons have always been my favorite car. Currently I own a '79 245DL rally wagon, I think I am 3rd owner.
Engine's strong, first new clutch is in, A couple years ago I learned about the fuse box, which I found hilarious. Had to face down my brother who would have worn out the crank trying to start it, because he'd never heard of a fuse problem in a car.
Current issues;The recently still nice original carpet has incurred ruinous damage between the front seats, and the speedometer has been disconnected, with 209,500 on. It's probably closer to 212,000: So far haven't found anyone who knows how to reconnect the wiring.
The roof rack seems rickety, although I can't find a specific point of weakness. Is it supposed to have a little movement from side to side, for some engineering genius reason that would naturally escape me?

Again, thanks and Hello.

not 100% sure on a 79, but the racks on the later cars are held in place with rubber expansion plugs that go into holes in the roof.

also not 100% sure, but I believe very early 240s like your 79 used a mechanical speedometer rather than an electronic one. later model cars had an electrical speed pickup in the differential 'pumpkin'... but the mechanical speedos use a rotating bowden cable which with age and neglect is prone to rusting and breaking... I don't remember if they pick the speed up from a front wheel or what.

The mechanical speedo picks the signal from the transmission, not hard to diagnose. Probably the cable is rusted or broken.
Luggage racks were dealer item, and usually cheap and ratlly, I remove them and junk them. IPD sells plugs to fit into the holes.
I'd fix any rust ASAP if you care to keep the car for any length of time... I'd inspect the rest of the body for other rust spots.

that makes perfect sense about the speed cable. The little tacho and the oil gauge and even the clock operate. Thank you.

Done and done. Addressed. Thanks!
As to the luggage rack, there's a little play in the crossbar but the mounts are quite firmly placed and take a lot of weight. I'll consider the plugs.

Ok, I can help with the speedometer. one end is a cable connected to the back of the instrument cluster. since yours is cable driven. this cable goes down the car and then into the transmission. check to make sure it is all connected and held on. if it is you might either need a new speedometer cable or maybe a new unit in the cluster.
