Blower stopped working; replaced fuse (#24 - 30 amp) and still isn't working!

I would have to say it's the switch on the console, possibly the wiring from the switch to the relay maybe?

Yes there is but you can use a test light at blower motor. Simple power and ground test. If test is good replace motor. If no ground replace your resistor

If its not blowing air then you may want to try a new blower motor if it is blowing air then you probably need a new thermostat

there is a TSB for a noisy blower motor and not working except on Hi, both cover under 36K miles, repair includes replacing blower motor and or resistor block and harness, judging your problem can be a bad resistor block and harness. hope it helps

I would check my fuses and relays first with a fuse tester. it cost almost nothing to check and may very well be the problem. if all is well try replacing the switches first as it's cheaper than the blower motor. if the switch isn't the problem return it to the store and get a new blower motor. I would think though if you have done anything at all electrically such as stereo etc.etc. it may be a fuse or you forgot to plug something back in

Check to see if the fuses to both your Windows and Blower-Motor isn't blown. The fuse-box is under the little door on the end of the dash on your Dodge RAM.

The reason I'm suggesting the fuses, is because you say that your "windows" doesn't work, and since it's all of them you're talking about, this might be the issue.

If the fuses isn't blown, then check to see if you might have disconnected the cables to your windows and the blower-motor :-)

Hope this helps!

Hi, since the whole panel is dead, I would check the 40 amp HVAC BLOWER fuse under the hood. Please get back to me if either that isn't the problem or the fuse blows again.

more than likely....blower motor resistor, normally located next to blower motor passenger
side under dash 2 screws & a plug

Blown Fuse

• Usually the first thing to inspect when the blower fan stops working is the fuses to see if any are blown. Locate the 10A cluster fuse or the 25A HVAC fuse in your car manual, and examine them to determine if they need replacing. The car owner's manual will tell you where to find the fuses that are connected to the heat and/or air conditioning. On the interior fuse panel of the car, a 30 amp fuse is labeled "Heater" or "HVAC."
  

Bad Blower MotorIf the fan only works on setting number 3 or 4, or just on the highest setting, it is most likely that your blower motor is failing and is about to die. Use a voltmeter to test the amount of voltage at the blower motor connector with your ignition on and AC running. If it reads 12V, the motor needs replacing.Automatic Climate Control SystemAnother thing that causes the blower fan to malfunction is the Automatic Climate Control System (ACCS). If the ACCS's settings are off, it may cause the fan to stop working. If it is the climate control on the car, typically it is a bad thermostat or electrical circuit that is the culprit.

If you pulled the 10 amp fuse in the I/P fuse block and the blower still worked than the the blower motor module is most likely the problem. It is fed by a 30 amp fus4e in the fuse block under the rear seat. That fuse is always hot and always supply power to the blower motor module. If you pull that fuse and the blower stops than it's pretty likely the blower module is the problem.

The blower module is located near the blower motor. It is usually held in place with 2 screws and will have four or five wires at the connector.
