On a 1988 300sel, my cruise switch on the steering column flops around now,and activating the cruise is next to impossible. Is it possible to remove/repair/replace the switch? I guess I'm afraid of the air bag. I read somewhere that a small bearing in the base of the handle becomes displaced and can be re-set somehow. Any suggestions? I also read of James Stephens heating problem in his 300sel. Like him, I get no heat unless I shut down the engine after it warms up, then restart. But any heat if any at all is very minimal. Could you further describe this "mono-valve",and it's location? Thanks-BTW the brakes are still working!! Thanks again. Nick
