Fuel filter replace several months ago. Engine overhaul 2 years ago. I've owned the vehicle for 10 years and have maintained it very well.

the inside and outside temp display stya,s on -37 deg and the left side intereior heating stay open

My transmission "clunks" when I let off the gas. I have replaced the driveshaft and the bearing that holds it. It sound like it would be a universal joint problem but it is not. Is there a fix for this?

How do locate the valves for recharging the AC?

oil change
