First post - so be gentle! The car is a 2004 330Ci Convertible...
Post a visit to a car valet, I have experienced several odd occrances with the mirrors/windows of the car:
The electric mirrors do not function/adjust
The fold-away mirror switch does not work
The one-touch power-up for the front windows does not work
The passenger-side mirror DOES tilt when the car reverses
I have checked fuses 31 and 57; fues 57 is fine, but there is no fuse in 31. Is this correct?
Day one after the incident, I assumed there was an ingress of water, so dropped the top off the car and about an hour later in an attempt to 'dry' the car out, everything started to work again. Job done - I thought - but next day the mirrors would not adjust. Following weekend, repeat taking the roof down process, this time the only 'improvement' was that the passenger side mirror tilts when reversing, but I cannot switch this off. Tried to use a hairdryer to 'remove' any condensation around the mirror switches. All to no avail.
Also, I have checked fuses 31 and 57; but there is only a fuse in 57. Is this correct?
Any ideas? Is the only option to take it to a main dealer to run diagnostics? I got a quote that diagnostics alone would be £84+VAT; althought they 'guarenteed' to find the fault.
