Unhappy Xsara Picasso 2002 HDI, no heater blower motor.

Hi All

I hope someone can help, unfortunately I bought a 2002 xsara Picasso 2.0 HDI yesterday, the guy told me the heater blower does not work (but it will only be the fuse), I have also realised that the A/C light does not come on when you press the switch, I have checked the fuses they seem ok but not sure which one to look at, I bought a Haynes comic today a little better than useless, does it sound serious?? or maybe a simple solution, can anyone help please.

Hi, There are no less than ten fuses covering the air-con system in it's entirety. Their positions change almost month-by-month from 2000 onwards.

The one most related to the fan is a 40 amp one in the engine-bay box. Consult your handbook for it's exact position, maybe found R/H side in car fuse box at top, if no b+ at fuse add a b+ fuse link to see if all is working, also check for over high current of the heater motor, we have checked motors at 0.8 ohm.

Possible causes of blower failure on these are; Ignition switch failure of one circuit; fan speed regulator or resistor fault; or the motor itself has failed.
Access to the motor is from pass side, up behind glovebox.

Had one of these last month same fault, I had no power to the fuse and it was the ignition switch.

go to the blower motor and you will see the wiring with 4 cables......one black one red and two thin cables.......to the red you must have +12volts after the car start......to black you must have ground and the two thin cables go to the blower motor switch.....if you dont have +12volts to the red cable after start then is fuse or the ignition switch......if you have properly volts and dont work the ckeck the blower motor inside
