Hi All,

This is most likely a problem with the amplifier. A lot of the vacuum units I test have this failure mode.

001 545 21 32 is most likely the part number on this unit.

The 005 545 12 32 units didnt come out until the mid 80s so unless the unit was replaced its likely the 21 32.

The gas powered cars had 001 545 06 32, 001 545 20 32.

Manual transmission cars had 001 545 70 32.

Redpeople, if you are interested in having the amp tested/repaired, just drop me an email at JamesDean59@gmail.com. I'm happy to help.

-Kris
