recently purchased a w124 300E in excellent condition. everything workin exceptionally except for three things.
1. cruise control. works sometimes, but then cuts out, or doesnt turn on.
2. a put a new stereo in, but cannot get it to function properly. it jitters when on CD, or radio. its as if it isnt getting sufficient power?
3. only the drivers side window works, the other three when operated short the circuit, cutting power to the engine.
seeing as all problems are electric, i wonder if they are linked? any information someone has on these problems would be much appreciated. thanks in advance!
