Second update: I replaced my heater core last night and it so far seems like that has cleared up my fogging issue. So lack of AC might be fine

Third Update: this may be no surprise to people that expect a car without AC but with working heater core, but it doesnt fog when it's me or me and my partner, but it's a damn miracle to me. Now I know my highschool (also without working ac) must've had a heater core leak.

Still the car does fog quite a bit in cold weather with 4-5 passengers in it.

Hey guys, new to the forum and Volvo world. Recently ran into the same exact issue here...compressor completely seized up on the way home and before digging around online I tried multiple belt combos, including double sided serpentine belt. Of course, no luck with anything so I accepted defeat. Smacknab I was wondering where you got the bracket from to replace the compressor with an idler now, since this car is just my work commuter and my 97 F350 is lots of $$$$ at the gas station. Awesome info on here fellas

Hey bhall,

Sorry to hear about your car! Do you have more info on your year/model? That might help others give some specific suggestions to your car.

To answer your question, I bought the bracket and flange screws (pulley to bracket) from volvopartswebstore.com. I bought the pulley in person from a Auto Parts International location in MA since they had that pulley cheaper than the Volvo parts webstore. You'll have to source the shorter bracket-to-engine bolts on your own. I got a few lengths of grade 8 bolts from home Depot with washers and tried my best.

More experienced members had suggested to me to put in a used compressor and call it a day, and I think that that solution is worth considering since you won't have to source these parts and it might come out a hair cheaper. Ozark Lee made a great point that if the AC hasn't internally torn itself apart, there shouldn't be metal bits in your lines and you might be able to just put a used unit in, clear the lines and recharge the AC.

If I could do it again I might personally choose to do the job properly and keep my car's AC as it might've only cost about $100-200 more (based on the price of a used compressor, new condensor and a vac/recharge for the AC lines). But at the time everything was breaking on the car and I was worried about any extra cost.

However you know what's best for your situation, and as my friend said, the AC can't break again if it doesn't exist.

The 1999 has a different serpentine belt routing, and the alternator turns counter clockwise , in contrast to the -1998 models. The 1999 alternator won’t out put if turned backwards.

Sourcing a used compressor off eBay is the fast path here. The 1999 AC compressor is also unique to the 1999 and 2000 models

I have a nuked one that won’t work for AC but will work as a pulley. Free for asking,

I’m working a project down at Duke this winter , if that’s close
