Did you have the same symptoms as I do? My front ac is cold but the rear isn't in the summer. This year we had a cold summer so didn't have many opportunities to try it but one day I sat with the truck idling and even the front ac got warm eventually but once I started driving it cooled down but I had it on it's highest setting. The rear heat works in the winter albeit it takes awhile to get warm though. I was wondering if it can also be the orifice tube or the TXV (thermal expansion valve) that I read in forums that also affect the performance of the ac system.
Thanks for the video good info just in case he has to be rebuilt.

Those are notorious for breaking- the plastic-yes plastic gears will break teeth occasionally. I've replaced 2 so far on my 03 Expy. Junkyards are a source also.
