M270 auto "02" plate purchased 8/2010, previously owned V class
Many thanks guys for the benefit of all your experinces on the V class. Your info enabled me to tackle today 2 jobs. First the dreaded pollen filter. Yes difficult to get at but worthwhile as now I can get a draft of air through. Took your advice and decided to leave the pollen filter off for the present. While in the mood decided to tackle the heater blower motor which had been getting slower and finally quit working. Couldn't cope with another hefty bill from Merc (just paid out £400+ to convert from air to rear steel springs) so managed with some difficulty to extract the blower. 2 of the 3 screws that hold the blower are reasonably accessable however the screw which is just behind the glove box was a swine to get out. Ideally a cross head screwdriver with a bendy shaft would make the screw removal more easy. On the bench connected up to 12 volts and could only get it to rotate slowly for a few seconds, however when shaken got it to blast away. The motor is held within the plastic housing by 3 rubber stoppers which can be released with a small flat screw driver. Once removed had a look at the brushes which are held in place by a spring which can be gently prised off. Underneath there is a short coiled spring which presses the brush against the commutator. The brushes quite badly worn also the comm was mucky. Once cleaned and new brushes soldered on the fan now works a treat.
