    I tried checking the fuses and banging on the blower. Fuses were good and the banging didn't work. Think it might be the switch. Thanks for the help

    first you will have to check for power to the blower motor with a test light the light will go off and on when you turn the switch of and on will confirm if the switch works if the light goes off and on it is not the switch i am still leaning tward the blower motor

Not sure what fuse or fuses you have replaced. I know there is a fuse marked BLWR in the fuse panel under the hood but the is also another fuse that is a vital part dealing with the blower motor working. Above in the second picture is the fuse layout in the fuse panel inside the truck. I marked the fuse you need to check (HTR A/C). If that fuse is good then you need to check where your power loss is. In the first picture above, that is one of the connectors on the control panel (power control switch &if you have a manual control not auto). The terminal marked with an arrow you need to chaeck for power at that terminal (Should be a brown wire. If no power, find the open wire from there to the HTR A/C fuse. If your good there you can make sure your getting power to the blower motor. Not sure of the wire color but it's the one that's not black. Make sure you have power there with the switch on. remember to use a seperate ground and not the other wire (the black one) on the connector at the blower motor. If no power the find the open wire from there to the replay. If all is good then there's much more tracing but I would start here. Hope it's just that other fuse. Hope this helps....

My 1991 has a back heater that suddenly quit working. Is there a fuse?


It uses the same fuse as the front heater blower. There is a ballist resister to allow for the different speeds of the motor that can fail and the blower motor is well known to fail too. Sometimes thers a fuse right in the wire thatr's connected to the blower motor it'self.

Heater does not work


Check heater fuse.
If fuse good - could be a failure of the blower fan motor or blower control switch.
If fuse bad - bad blower fan motor could have blown the fuse.
DO: check fuse, then blower motor.
Pricing: new blower motor: Duralast PM270 $43.99
new heater control switch: Duralast SW229 $46.99 (without
A/C).
I'd expect your blower resistor to be good - when they fail, the blower only will work on HIGH setting.

The blower motor for my 2005 Suburban suddenly


Check voltage at the terminal that connects the blower if the problem is the current blower because eventually the brushes wear out

The heater and air conditioner will not blow out any air


if the air started to work only on a few settings then the problem is your blower motor resistor if it just stopped all of a sudden then the blower motor is bad but the first thing i would check is the fuse. always check fuses first if you find a bad fuse for it and it pops rite after you put it in and turn the heater on then replace the blower motor

Heater blower fan not operating


First, check the fuse. If that is good, chances are the blower motor is in need of replacement.

Heater blower went out?


Either the blower went bad or the heater relay went bad. This does not sound like a heater core problem unless you where smelling a SWEET smell when it was running.

Air condition blower


I have an 01 convertible lxi that just did the same thing..... You can go to an auto parts store or in my case, I went to Firestone and had them replace the blower resistor. My air now works on all settings.
