The blower control module is located under the hood along the firewall.It is about a foot from the blower motor.(more towards the passenger side) It is harder to see as the relay center is directly above it.

A/C - Heater blower motor ! What make , model and year vehicle ? Manual or automatic climate control ? Could be a bad blower motor control module , a high blow relay contacts stuck closed .
RR/HVAC fuse 30amp located in the under hood fuse box. You can check it but highly doubt it's the problem . More then like it's the blower motor control module that's bad .
Circuit/System Description
The auxiliary blower motor is a variable speed fan. The HVAC control module controls the fan speed by sending a pulse width modulated signal to the auxiliary blower motor control module. The auxiliary blower motor control module varies the duty cycle across the auxiliary blower motor in relation to the pulse width modulated signal. The auxiliary blower motor speed can be adjusted from 10 percent to 90 percent duty cycle (PWM), 90 percent is high speed fan.
Watch this video for testing purpose's only , this is a front blower motor control module . Same way your back one works . GM is GM Chevy , Buick ,GMC , Cadillac .
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.
Yes, depending on if you have manual controls (Blower Motor Resistor) or automatic climate control ( Blower Motor Control Module), basically looks the same. Located on bottom of fan motor behind the glovebox. Need to remove plastic kick guard on bottom and look up. It's right there attached at bottom with 2 small screws. Must drop the glovebox door also, just release it down to get to the connectors into the blower itself.
The only way for the blower to still get power with the key off...means the resistor to the blower motor is bad...The resistor is located on the firewall...under the plastic shroud...this should fix your problem...nice Buick...:)
there is a module that controls the motor located arend the blower moter that will need to be replaced. Not sure if this is available other than dealer. check with auto parts stores first. I would ask for blower motor control module.If this helps please reply and good luck
the blower motor is under the glove box,turn the key on then the blower switch to high and check with test light.if no power check the blower motor resistor.
The blower resistor is part of the blower module which is located on top of the blowercase under the hood. Just by the blower motor , hope you find it.. It will also have 2 plugs on it..
Blower running all the time, even with the key out is a dead ringer symptom of a bad blower motor speed control. Replace that an your blower problems will disappear. See post below. For manual, call your local library and ask if they have online access to repair manuals.
The BLOWER MODULE is located on the A/C EVAPORATOR housing located UNDER THE HOOD passenger side firewall. Has 2 electrical connectors. Mounted with 4 screw bolts.Hope this helps
