Dear friends,

I recently had work done on the above car, ac compressor, ac hoses, driver window motor.

When picking car up, Gas pump relay did not work & replaced.
Immediately after, AC relay did not work & shop has not been able to identify the trouble. AC works when you do a direct bridge without relay, so trouble is related to signal from relay somehow.

Any suggestions ?
Any suggestions for a knowledgeable & reasonable older benz models mechanic in Miami Dade County ?
Thanks very much.
Jorge
