A/C appears to be working (dash light on) but fan only comes on when I go over rough corrugations.

Hi,

This truck isn't offered in the US, but I will try to help. It sounds like the problem is related to the connector at the blower motor resister. It should be located behind the glove box and mounted to the HVAC housing. I suspect that either the connector is loose or corroded or the resister itself is going bad.

I attached a picture below from a Mitsubishi Raider. It's the closest thing I have. Check behind the glove box for this connection and let me know what you find.

Take care,
Joe
