Finally have an answer on this one!! Turns out that there is a junction block under the dash on the RH side (J/B No. 3) that has a series of connectors (3A-3E); two of the wires in 3D and 3E (pin 3 in both of them, coincidentally!!) were loose. Found this on accident when talking to the dealer. Additionally, my wife noticed that the R and D indicators on the shifter and in the instrument cluster weren't lighting. Maybe related, maybe not. Talked to the guy at the dealership and after a few false starts, started fault tracing. TA DA! Problem fixed. Now we have A/C in drive and the lights on the shifter and the instrument panel are on again.

We have a 2004 GX470 and have a weird problem. When the vehicle is Park, the A/C blows cold. When we put it in Drive, it starts blowing less cold. We found out that in Drive, the clutch on the front of the compressor disengages. We tested the relay for the clutch and it works. Any ideas? It's freaking hot outside and the kids want A/C. Thanks in advance
