1998 Infiniti QX4 3.3L transmission, transfer case VIN: JNRAR05Y6W
Thank you to those who responded this one is going to the bone yard. Turns out the trans is available from the dealer and comes with the transfer case. For @3500.00, with 10 hours labor the R&R the repair equals the value of the vehicle. I believe the first re...

1996 Lincoln Town Car 4.6L window regulator VIN: 1LWLM81W5V
well guys, thanks for your inputs. I checked and rechecked everything and I could'nt see where the problem might be. I think I'll install a camera on this car to see what the customer does wrong. Both windows work so good now I'll just have to wait and see. Th...

1996 Nissan Maxima GLE 3.0L Transmission VIN: JN1CA21DXT
Thank you all for some good ideas, some I have already checked but it's always good to go back to basics! The customer will drop the car off while she will be out of town, maybe I can nail this one then. As you know it's very hard to fix an intermittent prob...

The grand prix is fixed. Thank you to all who replied.It was a 134 system.The clue that I ignored was the gauges. It is basic ac mechanics that when high and low sides are the same or nearly the same the compressor is faulty. In this case we had replaced the c...
