Question about 2004 Chevrolet Silverado 1500 Crew Cab

2 Answers

Blower is not blowing and I realize I need to check the controls but need to know where the blower motor is.

I am not sure whether the blower motor for the ac is located on the firewall or under the dash. I could really use a diagram.

Its under your pass side dash but start with the resistor first put your blower motor on high and push around on your resistor under your glove box,if it will come on by moving it around its your resistor

To test this, first hot wire blower motor to a known good power source (battery works) If it comes on then its good. Then locate the resistor (usually looks like a flat oval piece of circutboard with several wires coming out of it. Remove and check that the small coils are intact. Then find the relay and check it for proper operation Last, check blower control...make sure switch has power in and out. (check fuse on fuse block first before anything...if blown, replace it if it blows in a short time change the motor...it is drawing too much amperage)

No Front Heat 2003 Dodge Caravan - Tried most everything


If I am understanding you correctly, the blower fan is not running. You will need to take things apart until you can get to the blower itself. (Or you could test for voltage at the blower control switch) But I am guessing it is the blower that has gone bad, not the switch. However, they usually get noisy, and then go bad. Test for 12 volts going into the blower motor. If you have voltage at the blower motor, and it doesn't run, replace the blower motor.

Why has my a/c stopped blowing


Could be a blown fuse or a problem with the blower motor or resistor/controller, but on the AZC (automatic zone control) system, many times the problem is a melted connector on the blower motor controller. Look up in the passengers footwell area, there you will find the blower motor (fastened with three screws) and next to it the blower motor controller..

Check the fuse for the blower motor. If its okay, check for power at the heater motor. If you have power, and no blow, the blower motor will need to be replaced.

Ac stopped blowing any type of air


things to check; blower fuse, blower relay, fan control, blower motor resistor, blower motor.

You can check for power at the plug for the blower motor and back track from there. If you have power at the plug then you need to replace the blower. A cheap 12V probe tester will tell you everything you need to know. Let me know your findings and we can narrow down the possibilities

OK. So the blower notor isn't operating. Do you have power to the blower motor? The resistor is new from what I got. If you don't have power to the blower motor, then check the speed control switch and fuses. If you have power at the blower motor, replace the blower motor

Check the blower motor speed control resistor pack is ok.
(The resistor pack is usually located in the blower fan ducting in the air flow).
Check condition of electrical connection terminals on the blower motor circuit - these terminals pass considerable current and over time may fatigue overheat and loosen.
Check operation/replace any blower motor control relay,
Check the blower motor will run if +12v directly applied to the blower motor.
Check operation of the blower motor speed control switch is ok.

Blower motor doesn't blow anymore, This blows


If it blows only on high speed, it is the resister.
If it does not work at all, check fuses first. See owner manual for location.
Then check blower motor by jumping 12 volts from battery to blower motor. Make sure ground is jumped too.

If it works now, it's the control panel. If not, it is the motor.

Heater Blower Motor Switch Resistor(s)
The front heater blower motor switch resistor has the following features:
  • The assembly is located in the engine compartment on the evaporator housing (19850) next to the blower motor assembly (19805).
  • Three resistor elements are mounted on the resistor board to provide four blower motor speeds.
  • Depending on the heater blower motor switch position, series resistance is added or bypassed in the A/C blower motor circuit to decrease or increase A/C blower motor speed.
  • An overheating device (thermal limiter) will open the resistor coil circuit when the temperature reaches 121°C (250°F), interrupting the blower motor operation in all speeds except high.
  • The thermal limiter cannot be reset and is not serviceable.

Blower motor worked sporadically, then not at all


The fan motor will need to be replaced. You can access it at the firewall. There will be 3 screws holding it on. The brushes inside the motor are shot and will need to be replaced. You can also hit up a junk yard.
If the brushes are shorted out, then the motor will short out causing you to blow fuse.

Sounds like a blower motor not turning the blower. Could be elecrical. Check fuses that control the blower motor or blower motor relay. If these seem to be okay, locate the blower motor relay and try replacing it with a known working relay of the same style. If the A/C begins to blow, then you need a new relay. If not, you'll be looking into the blower motor or fan. Make sure your cooling fans function while your A/C is engaged.
