Air blower, dead battery

You will need to replace the fan speed control unit, located at behide the glove box mounted to the fan motor itself if u have the acc[automatic control panel] type, but if u have the mcc [manual control panel] type it will be mounted all most in the same area but further up near the firewall.

I dont think its all the same issue with the lights and blower. You will need to do some trouble shooting. Do you have a multimeter to do some testing?

Your car does not have a speed resistor like older cars it has a blower motor speed controller instead more of a solid start device that works better. It is located under the dash on the passengers side.

Here is a some guides (below) to show you were it is and what it looks like.

Please let us know if you need anything else to get the problem fixed.

Cheers, Ken

Power the blower motor direct from the battery and see what happens if it comes on-check blower relay, resistor and blower switch

Do this first to find out if this was the cause for the fan motor been inop, lift hood on passenger side lift crowl cover & remove cabin filter, now pour water on windshield & allow to run on top of cabin filter housing, if water runs behide where the cabin filter element would fit, if so then u have water getting inside the car & causing damage to the fan speed risistor & possible fan motor, good luck.

Need to know if your car is a old body style or new body style, if old body style u need to remove engine cowl cover to gain access to fan motor, & if new body style u only need to remove glovebox nothing else.

You could test fuses relays and wiring sockets for power to find where the problem is?

U need a fan speed control unit, this is located behide the glove box & mounted to the blower motor assembly, also check if u have water intrusion from cabin filter housing, do this by first putting wipers on park position, how? Turn ign key on then off after doing that hold wiper switch down untill u see wiper point upward release switch & wiper is now in park, now lift hood & lift crowl cover on the passenger side, there u should see the cabin filter & housing, take filter out & pour some water on the glass allowing it to run on top of housing, if u see water entering housing where filter sits then u will need to repair that cause that may be the cause for your fan speed control unit to go bad it may also cause your fan motor to stick, good luck.

Open the bonnet, take out the pollen filter and stick your hand down the back. This will allow you to see if the fan motor is seized. To get the fan out you have to take the glove box out and dismantle from inside the passenger footwell. The motor is a Siemens unit made in France. It has a steel shaft running in steel bushes allowing corrosion seizing !

This is a ray of hope for you, you will need to replace the fan speed control unit mount on the p/s, you will have to remove the glove box to reach it, also you do not have to remove the dash at all to replace the fan motor if need, the fan motor is remove from inside the eng bay upper area after removing the crowl cover, roughly a 4 hour paying job but it only takes 1 to 1.5 hour for complete job

You will need a fan switch control module bolted to the heater box on the p/s bolted riteon the cover where you would open to see the evaporator assembly if you have a acc control panel, if you have a manual control panel then you would have to replace the fan speed resistor bolted where you fan motor is
