Review on Enhance Your Vehicle's Performance with GM Genuine Parts 89059275 Transfer Case Four Wheel Drive Actuator and Encoder Motor by Chase Shetler

My opinion is not for sale. Bought this way to fix my 4WD which the mechanic told me the encoder motor was bad. Bought this after reading to use as Delco only to avoid problems. But the price was good. I installed the motor and the 4WD still doesn't work, so of course I say OK, something else is bad. After talking and reading with people, I changed a switch on the dash that said it could cause problems, not bones. Then he changed the front actuator, no dice. Eventually there is only one part left that must be a TCCM problem, an expensive part around $200. Bought and installed, guess what didn't work yet. Then I was told to check the area, I did my best but had to clarify it due to the complexity. Took it to my mechanic who also drove around to no avail. They ended up thinking the engine was bad, but when they found out I had put a new one in, they didn't really care. Well they tested it and it was bad. After $500 I have 4WD again. If I had a good motor, the problem would be solved. In any case I tried to contact the seller for a replacement as AcDelco has a 12,000 mile 12 month no response guarantee. The mechanic said the engine was NOT AcDelco. My word to you is NOT TO BUY! Others got lucky I think but in my opinion they weren't worth the risk. The $200 self-repair cost me about $850 in installments, not to mention the time.
