Hi everyone,

This is an issue I inherited and Land Rover could not figure it out. When you turn the rear air on with rear control, everything activated and works except the fan. The fan has been tested and is good and the relays have been checked thereby stumping the dealership. Has anyone had an issue similar. Also the front air does the same thing periodically where you turn the **** and no fan. Turn it off and on and it will work and is worse in the winter. The relays under the hood are new. Anywhere else to look? It is an LR3!

Thank You!

 

The rear air control has a module between it and the motor. That module has an earth ground. I'd check the ground, then the module. Schematic attached for the shop manual.

 

Do you know the physical location?
