No AC blower...

[voyageur]

1999 Discovery II...

Car has been parked for a week (my medical issue) and when we started it, everything on the digital A/C display looked fine. Compressor engaged, electric (auxiliary) cooling fans turned on as normal, digital display showed proper symbols, but the fan will not run on any setting. The fan speed symbol changes, (assume switch is good) as designed with each successive press of the fan button but... no fan. I checked both the AC blower fuse (10 amp, under steering wheel fuse box) and the heater fan fuse (30 amp). Both are good...

I do have a FC 21 and 22 (Sunlight sensor) error code. Can the sensor be changed? Could that prevent blower operation?

Car just had a full tune-up and an oil change...

Any thoughts on the next item to check since both fuses are good?

Thanks...

The blower motor can be accessed by removing the passenger side under dash panel. 3 "fir tree" style clips hold it in place. Remove those and lower the panel and you will be able to see the bottom of the motor. It has a 2 pin connector on it, one power the other ground. Turn the climate control on and dial up the blower speed and check for power at the motor. I have replaced several blower motor relays for this problem. If there is no power there that is what I would suspect. If there is power, verify the other pin is grounded and if it I would get a new blower motor. The solar sensor won't inhibit the blower motor. I seem to remember that the solar sensor faults are normally stored under certain conditions, but I don't remember whay or why.

Bad under dash fuse panel

Bypassed two bad pins on the fuse panel and added a 25 amp inline fuse.

Problem solved. Found the solution on "Land Rover Forums".
