That's probably why MB took out the economy guage. Mine doesn't have one. I understand vacuum is involved in almost all the power stuff in the car such as trans, power locks, steering, etc. Am a mechanical moron, don't have a clue how it works. My son recently graduated cum laude BSEE, maybe he can educate me on this. Anyhow, many many thanks to you people out there for your insights and care specially to 95E320cab who called and offered his valuable time to help in person change the resistor ends. I was floored by his generosity. I will change the resistor ends and will post the results.
Is there a similar forum on Acura cars? My wife drives a 97 RL with 84k. Yesterday, after a sudden brake to avoid an accident, there now is a grounding noise when braking a little harder than normal. Noise doesn't sound on normal braking. Could this be a simple brake pad replacement?
