accessing A-C/Heater Blower Motor 1986 300E (W124)

[thurat]

Hello, I have a 1986 Mercedes 300e that the blower is not working on. First I am trying to figure out where the physical blower motor is located and how it is accessed. Second I am hoping, someone might have had or know what this problem is and how to correctly fix it.

Most time the blower will not come on for heat or air at all and it seems that the only time it does come on is after that car is quite well warmed up. If I have drove it for 30 or 40 minutes and then turn the car off and restart then the blower will come on and the system acts very close to normal. Of course my normal commute is less than 30 minutes so I do it without heat/air. This has been going on for about a year steadily getting worse.

The majority of the time the controls do nothing. You can press them and turn them any way to want and it makes no changes. Nothing comes on, nothing happens, no clicks, noice, air, or any other indications that something is happening. I would not want to haul it in to my local dealer as I don't want to get into a situation where I have to keep spending money to get out of it.

Thank you everyone for any help or insight you can give.
