I have a 93 940 volvo i have no climate controls
These ones were weird. The button sometimes had to be pushed IN to turn on the A/C and sometimes in the OUT position for it to be on. The manual (accessible on volvocars.com website) will tell you which one you have.
If you don't get cold air, you should listed for the loud click under the hood of the A/C compressor starting and stopping. If you don't hear that, it's very likely that you don't have enough R134a refrigerant in the system. Sometimes a recharge is all you need, and sometimes you have a bad leak and need a system repair.
Listening for that click is key, and if you don't hear it, check the charge level at the nipple under the h
Noisy engine when cold
Sounds like low oil pressure, there should be a check ball valve in the pump it may be stuck in the open position or the spring that holds it may be weak. Try 20/50 Castrol GTX and a quart of slick 50 with a new oil filter. If it still makes noise when cold it will be time for an engine rebuild in the near future.

Whereiscraqnksensor
The crank angle sensor is located on the top of the transmission bellhousing, mounting bolt is a 10mm bolt, bottom left side (if you are looking at the engine with the intake on the right) and is very hard to see. CAUTION: Do not apply much force on removal or installation of the sensor bolt as its bracket is very fragile. If the bracket gets distorted it could cause a no-start condition as the AC sine is too weak to be detected by the ignition computer. Also, work on the system powered down. Remove that battery negative cable!
Brake lights won't come on changed switch and
Remove the brakelight bulb holder, If you pop out the entire assembly it will save your knucles some skin. Then you want to take some fine sandpaper and clean the contacts "on the housing" well, and coat the with a thin film of dielctric grease or vaseline. I'm sure this will resolve your problem. I've had to do this to numerous Volvo vehicles over the years. Also once you're finished, the dash indicator may "not" go out unless you purchase the bulbs from Hella because of their candlepower exclusivity.
