    A friend of mine has a 2004 Impala that cant get his blower to turn off, when the keys are out of the ignition. The radio will stay on as well.

    I suspect an issue with 1 or more relays, but dont know for sure. Wish someone had a solution for this. I need a schematic to locate all the relays.

Your blower motor resistor is shorted and needs to be replaced it is located on the blower box and has 5 or 6 wires going to it there should be two small 7 mm bolts holding it down, you can pull the blower motor relay to shut it off for now untill you get a replacment resistor good luck and please rate -jeff

    Sometimes it is NOT the resistor that causes this malfunction. Someone needs to post what happens if it is NOT the resitor... then where do you go?

    I'm on my second resistor. Replaced the motor. Worked fine for a week. Pulled into work today and sure enough motor went full blast and now it's stuck on.

My blower motor quit working changed blower and now it runs all the time even with key off worked fine before blower went out the fuse had also blown what could cause it to run all the time now


Most would say it is the Blower Motor Resistor or a relay..And possibly the dash heater control knob..However it is running all the time even with key off..This means it is getting power all the time from somewhere..It sounds as if wiring is crossed..Did you have to change wiring plug in connectors..?..

I cant turn the heater off, it runs all the time


Sounds like the blower motor control module has gone bad. You can find the module under the passenger side of the dash next the blower motor. Power is supplied to the module all the time. If the module fails it can turn on the blower regardless of the key position.

Blower motor runs all time


Either the blower motor relay is stuck closed and running all the time.Relay should be under the hood. Look in the owners manual for the location. Also does it shut off with key or continue to run, Most likely a stuck blower motor relay.

Blower does not run all the time


The blower motor is located under the hood on the passenger side. With the key in the run position and the blower motor switch set on high tap the blower motor with the plastic end of a screwdriver. If it starts to work replace it. If it doesn't start to work check to make sure it has power and a good ground.

Vent fan running all the time even with key out of switch


You have a bad blower motor relay, when the relay goes bad. It can freeze in the on position keeping the contact closed to run your blower motor. Inspect the blower motor relay and wire harness for any short due to burnt wire, this is a common issue with that year of Silverado's
Thank you for using fixya and good luck.

Heater airconditioner blower motor runs all the time without ignition switch in run position . runs without the key in the switch. the only way to turn it off is to remove the fuse that powers the blower...


If you haven't fixed this yet, your Blower motor resister module is bad. It is located to the left of the blower motor and mounted in the A/C air box. Just pull the right kick panel down and you will see it.

HEATER BLOWER MOTOR NOT COMING ON THE BLOWER MOTOR IS GETTING POWER TO THE CENTER BROWN WIRE BUT IT ALSO HAS A BLACK WIRE THE SAME GAUGE AS THE BROWN CENTER WIRE AND A SMALL GAUGE BLACK WIRE ON THE OTHER...


at blower motor connection, disconnect wires and run a 12v line to the positive side of motor and ground the other side if need be. if motor runs then you have a fuse or a wire problem. if it does not run. then blower motor is bad.

Blower motor continues to run when vehicle is off


Your problem is the Relay which is encased inside the Heater/AC Resistor Module. This is a very common problem with GMC and Chevy Trucks. The Relay's return spring fails and the relay is held closed by gravity. The only fix is to replace the Resistor Module. I have a 2004 Silverado and have replaced the Module 3 times and the Blower Motor twice. The Orange wire feeding the Module is always Hot (12V) and feeds the Relay Contact for Highest Blower Speed. Hence the Blower runs all the time even with the Key off and removed.
