- 2006 Rendezvous
The climate control module (manual version) stopped working on my 2006 CX. Nothing on the panel works (blower, A/C, vent selector, rear window heater) but the radio and other accessories are operational. I installed a used climate control module and it did not work. I took my Rendezvous to my mechanic and he diagnosed the problem as a faulty ignition relay. He replaced the relay and now everything on the panel is now working. He cod not explain why everything else controlled by the relay was working but not the climate control module. I wanted to pass this information to everyone in the Rendezvous forum.
