The OVP on these cars are notorious.

I just spend the $60 and replace them if there's any question. If it doesn't change the symptoms, I've gained a spare for something that will fail.

Is the OVP probably OK if the A/C works fine but the Tach does not work? This is my situation. My cruise control is out too.

Cruise out with something else is likely a coincidence, the cruise is often out on the older cars (what year and model?). Tachometer could be the crank position sensor.

Well I have a 93 300D. I am patiently waiting for my maintenance manual to arrive so that I can then start diagnosing my problems.

Again thanks for all the help could not have done it without all the suggestions
Can you explain how you jumped the relay in a little more detail? I've had the same issue, but ruled out the OVP as the fuse was not blown. I currently have the KLIMA bypassed to get my AC to work, but that's not a solution.

This will not work on my car. How did the original poster in this thread test his?
