Oh man. Do you have any idea how fantastic it is to have you guys for a resource? I mean, I can pull apart an old 302 blindfolded, but I have shied away from these newer engines with their computers and the way they stuff so much in such a small space. I used to be able to sit in the engine compartment of my old LTD and work on thatsmall block V8for hours with nary a bruised knuckle, but no more.
I do have one more question if you can put up with my lack of knowledge about A/C (never had that in my LTD). Do I need to purge the system to replace the low pressure switch? It's on a pipe of course, but truth to tell, I have no idea if there is refrigerant in the pipe or if removing the switch would allow it to escape if there is.
Thanks much,
Brian

Nope, you'll be fine replacing the switch without purging it. (It resembles the tire stem where you pump up your tires.) There's a rod in the center that is pushed down as the switch screws on to open the valve. It's a very simple replacement.
Anyway, I'm glad to help. Luckily I know about this because I just did this job recently. I like tinkering with cars, but it would be nice to get a little more sometimes. My other car is a Mitsubishi Eclipse, so there is no room at all! When I changed my timing belt, I had to choose between completely removing the engine or drilling a hole in the wheel well to get one of the bolts out... I drilled the hole because I don't have anything to mount the engine on. I had already removed two of the three engine mounts to raise and lower it as far as possible, but it just was too long. So the Volvo feels a bit more roomy to me.
I need to do the same thing with my '03 s40. How do I remove the glovebox? I noticed mine is different from your 99.
As mentioned in the S40 forum, on your car you don't need to remove the glovebox. Everything is accessible from below, once your remove the "passenger side soundproofing" panel above the footwell) Check your previous post in the S40 forum; instructions were there on how to troubleshoot and see if it's the (relatively) inexpensive resistor, or the (more expensive) blower.
