AC blower works intermittently
Hi all
need some advise
AC blower wants to blow intermittently
the diagram doesn't list the blower fuse or relay
there the fuse box on the driver side in the engine compartment
i shook the relays
no change
If It's the blower motor under passenger dash then I can replace but wanting some advice
thx

under the bonnet pull out the battery - remove its mounting bracket - 2 bolts - clean the gunk up, unblock the plastic gutter pipe from edge of the screen running in to the inner wing
then pull back the carpet inside and sort the corrosion mess and puddle - then look up at the blower motor and sort that
the module to control the AC sits beside the fan - the side away from the inner wing - I believe its the connection or brushes sitting on top of the fan that cause the fan to give up - on most Mercs its at the top of the fan ready to get wet
