Aircon - No blower motor
99.9% of the time its down to this bit
It's a resistor pack that controls the voltage to the motor to allow a range of speeds - it can be found in front of the fan motor mounted vertically in the heater box and is held in with two screws.
This might help location and the part number for a new one may be readable (or may not!!) 90230931
So I just buy a new one fit it and job done? - Actually no I wouldn't advise that - you would be wasting your money in most cases.
The unit in most cases is fine just this bit is broken
Continued in summary section so jump to that
No Aircon - No Blower motor
99.9% of the time its down to this bit
It's a resistor pack that controls the voltage to the motor to allow a range of speeds - it can be found piggy backed on top of the fan motor in the heater box and is clipped on.
So I just buy a new one fit it and job done - Actually no I wouldn't advise that - you would be wasting your money in most cases.
The unit in most cases is fine just this bit is broken
Summary
So in both cases I'm just talking about the bit the red arrow is pointing to
So what is it? - It's a thermal overload resistor
What does it do? - For years and years nothing - but then it breaks when the motor is old and sucks a bit to much current/Amps (it's a use once part)
So why can't I fit a new one - Cos it will fail quicky just like the original has done recently due to the blower motor being a bit old and drawing more current and Vauxhall won't give you your money back but will say it's your blower motor that needs to be replaced
So what can I do?
Fix the problem
Get your self a little section of heatshrink or some insulation tape and a household wire joining block (you know the brass or steel blocks that have two little screws to tighten down on a wire and make a join)
Cut the thermal overload resistor in half at the middle of the blob
Break the ceramic away till you are left with two wire ends
Join the two with the chocolate block
Insulate from contact with any metal parts or damp
Fit and forget it.
Oh and the other 0.01% it's down to the switch not working but that doesn't need much explaination does it?
On second thoughts - For a Carlton ONLY!
I don't think they will be high enough resolution but if you right click and save as you should be able to view them on your PC and read em OK
Edited to Add
One important point
The information above only relates to total failure of the blower fan motor - if you've just lost a speed or two then replace the part above - it is however your choice if you modify a new one to save you having to pull it all apart later
