Where is the heater blower motor located on a 1991 mercedes benz 190e 2.3

If it wont turn over try the neutral safety switch, if it wont start in neutral either the switch most likely needs to be replaced.

hi it down under the wiper motor

If the heater is not working (fan is not turning), but you are able to press the climate control buttons to activate the AC and venting, then the relay (actually this is the ACC in the dash with the buttons, there is no separate relay that controls the AC/Heater fan) is not the problem. Check the fuse box in the right side engine compartment, then check the long 3A flat fuse located in a coverd case atop the the wheel well in front of the fuse box. If these are okay, the fan motor is the problem. If the motor needs to be replaced, you'll need to remove the front cowl under the windshield, and also the windshield wiper assembly. The motors usually bind after 20+ years and need to be replaced. Sometimes, they will bind, then work again. Sometimes they'll bind and blow the long fuse. The job takes about 2 hours and the motor is about $150-$250.

Open your hood, look under wiper if you see dust filters you have them if not you dont. Its tough to remove the blades without breaking them i dont suggest it.

This link gives you step by step instruction on how to remove and install a blower motor:

Most likely the contacts on the blower motor are worn. Search on line for a repair kit for the "brushes" or buy a new motor.

hi,located under your wiper mechanism,remove wiper arm,plastic cover,blower motor is in front wall,ty

Hello, The blower motor is located below the windshield wiper assembly. You have to remove the plastic cover that below the windshield then remove the wiper assembly, then you will see the blower housing. Remove the screws from the housing then remove housing cover. Look close because some of the screws are hard to see. Once you get the cover off, you will see the motor and there is a metal strap that holds it down. Take a punch or whatever and stick it in hole in the strap and push down. Then the motor will come out.
I hope this helps.

IT'S THE HEATER CORE, IT IS LOCATED UNDER THE RAIN GUARD THINGY UNDER THE WIPER MOTOR

Check your Klima relay ,located behind the battery next to the ABS and Engine ECU ,sounds like the a/c compressor is not turning on
