Blower motor dodge ram 1500

AC blower works only when I seem to get the steering column in the "right" position ( which varies) and sometimes not at all. If and when I find the sweat spot sometimes works on all speeds yet other times cuts out when put on high. suspect loose or bad connection in wiring in column. Suggestions on identifying and resolving problem would be much appreciated.

I would agree, it sounds like a problem with the feed for the ac-blower coming out of the key switch.

SOURCE: HEAT/AC blower motor stopped working

It's even odd that you were getting a step-type voltage when you first checked.
Many speed regulators are simple tapped resistors with the switch selecting which tap is connected to the motor.
More elegant controls would use a semiconductor (transistor) and a few other components to supply step-variable voltage to the motor.

To determine which is used on your car, you will at least need the electrical diagram for it, preferably an aftermarket service manual - Haynes or Chilton should be available at least in the US and Canada.
Those will contain not only the electrical info you now lack but possibly instructions that will aid in locating the controlling circuit.
I suspect that circuit is faulty; if the resistor type, it will be a device with mulitple taps, if solid state, a few parts on a small board.

SOURCE: Climate Control Blower motor stopped working

I had the same problem with my 2000 Mercury Grand Marquis. I ended up replacing the blower and the resistor which is on the passenger center side of the firewall tucked in where it is hard to get to. Everything worked fine for about two years. It just went out again here about a month ago. I am going to try to replace the resistor again, but I am wondering if it doesnt have something to do with the climate control switch. I do not want to replace the same part every year or two, so if anyone has a idea of what could possibaly be the bigger problem, please let me know.

The motor is fine, the blower resistor is the most likely cause. All fan speeds except high go through the resistor.

SOURCE: how to change blower motor in a 2004 dodge ram

Good Evening. Unfortunately it could be the switch, or it could just be the blower motor resistor, which is where i would look for power coming out of to the blower motor first and foremost. I hope this helps your situation, and if you have aany jmore questions please feel free to ask.

Sparks under steering wheel of dodge ram 1500 2003

My blower on my 04 would randomly cut off but if you tilted the steering it would sometimes work again. Pulled the cover off the steering column and found that one off the connections(plug ins) was arking. Squeased connection closed a bit more with a small screw driver and put some electrical dilithium grease in it and haven't had a problem since.

04 dodge ram 2500 has no power going to blower motor

I don't know if this will be the same as my 96 but there is a bulletin from chrysler about these losing power at a relay above the steering column that is specifically for the blower motor. Call your local dodge dealer and ask them if your truck has a bulletin for this exact problem. Also there is a blower motor resistor held in by 2 screws right near the blower motor. Check there for power first.
I hope this helps.

I have an 03 Dodge Ram 2500. The ac blower motor stays on after the ignition is turned off. I can wiggle the key to make it turn off. Is this the ignition switch?

Blower motor for heat and ac would only come on when I messed with the tilt wheel. Now it wont work at all.

Try the ignition switch, dodge has them on backorder so there is a problem that just has not got big enough to recall. The switch is only $14.30 unless you have a V10. Mine started off as the turnsignals quit working unless you moved the tilt steering and the the heater would only work in the tilt up position.
