The variable speed in Blower is controled by a blower Regulator. It is near the blower. If you can locate the blower, ussually in the center of the console. It can be accessed from outside of the fire wall ( from engine side). Lift up the blower, the regulator has a triangular shape in the bottom of the blower. It is a lot of work to get to the regulator. Good luck.

Your problem is probably with the blower motor resistor.

Yes,could be your blower resistor is bad,it's right next to the blower motor,it controls the blower motor speed,easy to replace. Duralast Blower Motor Resistor Just took a guess at the model type since you didn't state,wow,high dollar price,guess it comes with a Mercedes,paid about 18 bucks for mine on my 85 Nissan.

Blower motor only runs on low for 2006 sprinter van


If your blower runs at low speed at the highest speed setting, it is more likely to be the motor rather than the resistor array. If it runs at low speed setting only then it is likely to be the resistor array.

2008 Honda Odyssey AC fan works on low and med speeds but no high speed blower


There should be a high speed blower relay that bypasses the resistor for slower speeds.
Check with an auto parts store or the dealer.

Idles low when ac/heat is on and lights dim


fix the idle speed to 850-900 rpm
check the alternator and voltage regulator as the voltage should read 14.5-14.8 volts dc at 1000rpm or higher regardless of what is running
have it bench tested by an accredited auto electrician

Brushes on the motor may be going bad. Blower motor is in engine compartment under wiper motor assembly. The blower motor regulator is under the blower motor. There is an A/C relay behind the fuse box under the screwed down cover.
for lack of motor speed its probably the brushes on the motor or the regulator. If no cold air your charge is probably to low to engage the compressor.
