I have a 2003 GMC Envoy and my issue is when I shut the blower off it still ... Can this issue also be remedied ...

2004 GMC ENVOY Blower Motor Control Module / Resistor

Common problem, replace your blower motor resistor. Located behind your glove box. Easy repair.

The relay in your blower motor is stuck on, there is a TSB for this issue. Replace the blower motor resistor and you'll be back in business.
How does the resistor get power if the fuse is pulled?
Replacing the resistor will cure both problems. TSB is a technical service bullitin seen below

You have a defective blower motor resistor pack or the wire harness/connector to the resistor pack is damaged. These items are located under the dash on the passenger side behind the glovebox.

You have three possible things left, check fuse #35 in the underhood fuse panel, wiring harness going to resistor pack (look for burnt wires or melted connector), or a bad blower motor.

SOUND LIKE BAD BLOWER MOTOR RESISTOR.CHECK BLOWER MOTOR HI BLOW FUSE AND RELAY.YOU WILL NEED OWNERS MANUAL IN GLOVE COMPARTMENT TO LOCATED BLOWER MOTOR FUSES AND RELAYS.

sounds like a blower motor resistor. it might just blown the fuse also(for resistor). Pick uo a chilton book at advanced auto or any auto parts store. They r like $12, it will show you where to find resistor and fuse.

First check and see if you have voltage at blower motor with key and switch on, with test light, if you do have voltage, blower motor bad, replace it, if you don't have voltage at blower motor, next to it, is where the blower motor resistor is at, follow the wire from the blower motor to it, check voltage there, should have voltage, if you do replace blower motor resistor, resistor cost about $45.00 at auto parts.If I can be of more help. please let me know.

The likely problem is the blower motor resistor pack is defective. It is located behind an access panel below the glovebox. Go to www.trailvoy.com and do a search on "blower motor resistor replacement"

ITS UNDER THE RIGHT INSTRUMENT PANEL.YOU HAVE TO MOVE THE GLOVE BOX DOOR.TO GET TO BLOWER MOTOR AND RELAY AND THE RESISTOR.
