w124 230te 1990 interior fan problem

[plainoldtrygve]

Have a problem with the interior fan. I dont know the engine number, but its a euro petrol 230te. it is not a AC heater/coolin system, its of the old fashioned type. there is still heat comming from the vents, but the fan must be broken in some way. Does anybody know if this is a common problem on these models, or have experience on where to easiest acsess this fan?
Any help is much appretiated.
