Mercedes A/c problems are legendary.

Your cruise control problem could be a Hall effect sensor in back of the speedometer, or an amplifier, or the main unit. But you need to explain your problems more fully before anyone can help you!

Thank you for the reply. I am having a few problems and I was looking for a few owners with experience with the 190 2.6 to establish a direct link...thats all.

Little history.....just bought my 92 190E 2.6 about a month ago with 130,000 miles. All maintenance up to 85,000 was done at the dealership according to the records. It is in pristine condition and was WELL taken care of. I feel I got and excellent deal ($4900).

My problems are that the A/C works great but the climate control center will not change the air flow from dash to the floor or both. Although the A/C works the heater does not.

Cruise control does not work at all. Wont turn on.

Shimmys at 60 mph (have read threads and think I can fix this one by replacing the wheel bearings and the front brakes...along with getting the tires balanced.)

Have read that a lot of the systems are vacume you think the heater and climate control are vacume problems.

If you have air flow through the center duct then you do not have a vacuum problem. That is you don't have a normal vacuum problem. I have seen systems rigged to just do A/C where the vacuum ran straight of the motor to the heater valve and the center vent.

It takes vacuum to close the heater valve and to open the center vents so it likely is present.

The push button controller activates switchover valves (vacuum gates) which are in one group behind the glove box. There are six or seven switch-over valves and they open and close the vacuum to the various vacuum elements.

To test one should have a vacuum and wiring schematic.
