The vehicle is repaired. Found out why the customer was so ADAMANT for an OE type repair. If I had come up with the proper malady, the extended warranty provier 'MIGHT' have paid. Unfortunately bags, compressor and control circuits are not covered (snicker, sn...

1969 Mercedes-Benz 280se 2.8L heater controls VIN: 108.18-12-
The heater controls are removed as instructed with one exception. It was not necessary to remove the instrument cluster. All the cables are in good shape, a little lube and they will be fine. The real binding is a combination of the controls themselves, the he...

Well Nick from Ohio nailed this one! After talking to the customer, I found out he liked to fill the tank right to the lid. So for the last few weeks he's just been rounding up to the next dollar when he fills it and all is well! Customer is very happy for not...
1996 Mercury Villager LS 3.0L Hesitation, Surge VIN: 142DV11W2T
I can't say that this van is fixed. The Fuel presure was in the spec KOER, dropped 2 PSI after two hours of engine off, plenty of volume, and almost doubled when pinched off return line. The spark KV was 25-30 on spark tester at coil wire and each plug wir...

1998 Oldsmobile 88 Royale 3.8L Cooling Systems VIN: 1G3HN52K7W
Most refered to the upper plenum problem which we had replaced with a NAPA replacement. I am suspicious of that replacement part but the customer has not returned to do any further work on this vehicle. Most likely it is performing ok: not using coolant, not o...
