E-420 1997 blower problem

[steparisse]

Both heat and a/c are working and so the digital display, the fuse is ok but the fan is not working; eventually the car gets either cold or hot depending on digital set up. Could be the blower motor that needs to be replaced?

Look for info by searching. Common problem sometimes caused by not keeping outside air filters cleasn which overheats the regulator. Easy to fix with a W140 part.

Get the Behr one when you do it is an improved version with significantly better heat sink properties.
