I have just replaced my Blower motor and regulator. I have also replaced the aux water pump. All seem to work fine except there are no illumination on the CCU. Does anyone know what could cause this? The CCu appears to work fine. The fan comes on and the speeds all work as well as the defrost and other buttons. Any ideas on where to start looking? Thanks.

It would help to know the model, but it is likely that the bulbs are either burned out or knocked loose when you replaced the blower switch.

Sorry it is a 87 TDT. I did not have the ccu out at all. It seems weird that all lights are out.

Have you tried turning the dimmer switch? Sometimes they get bumped and turned down.

Yup tried that. Is there any way that the ccu could have burned out and still work on most of the controls?

I think that the point here is that the lighting is powered by the dash lighting circuit, and will operate with the CCU fuse blown, independent systems. If the lights are out, the rest of the dash lights work, and the CCU operates, you've most likely got burned out bulbs.
