A/c heater blower on dodge 1 ton diesel

The blower on my dodge 2002 diesel truck makes a horrible noise when I turn it on high. On the other speeds it barely blows if at all. I think it just seeps out as opposed to blow out. Thus, I do not have a defroster which is quite aggravating in the winter. Does this mean I need to replace the blower and is that a diffcult job or something I can do myself?

Sounds like the blower bearings are dried out and shot..since most blowers are a sealed item now, yours will need removed and replaced.. on some rare occaisions, you may get away with squirting some wd40 into the housing the blower sets in and it will work for a short while but not be dependable as a repacement unit is.. instuctions are available from parts stores. and the old one may give you a core to return..good luck

SOURCE: heater blower makes noise on high speed

it is either a bad switch or window motor. finding a wiring diagram and shooting power to the correct wire will identify whether the switch or motor is faulty.

I have a 96 Intrepid, and none of the signal lights work. I tried replacing the fuse, but this did not remedy the problem. Could this be a loose connection?

IF THE BLOWER MOTOR ONLY WORKS PN HIGH THEN YOU NEED TO REPLACE THE BLOWER MOTOR RESISTOR LOCATED ON THE SAME HEATER BOX AS THE BLOWER MOTOR

SOURCE: Instructions to replace a blower motor in a 2005

It's located on the passenger side under the dash. There are 4 to 6 screws that hold it in. If you know for sure it is bad replace it, but it could be the resistor, it is located right beside it. these can go bad also. In most cases the blower will work on high, but not on lower settings, this would be the resistor, not the blower.
Good luck

My defrost air barely comes out or blows. my speed control has 1-4 speeds but only 2 works the others don't blow at all. what do you think is the problem ?


I had a truck that did this , it would only blow on the high speed setting , turns out that the AC drain was clogged and it allowed water to back up and rust blower motor shaft so it would only run in full blow mode and then it wouldn't blow very much then !!

Weak blower motor


Check good voltage and ground for blower motor. Actuators under the dash may be restricting air flow? High speed doesn't usually use a resister.
Check for hvac trouble codes, in my part of the country, some of the national brand autostores will check codes for free, if there are any.
If you think problem with blower motor, itself, replace it. Sometimes, you can remove blower motor, use jumper wires for voltage and ground, using inline fuse, come off the battery, see if it blows like you think it should?

A/c will not blow on high


Could be the high speed blower relay. On most models the lower speeds are controlled by the resistor and high is powered by a relay.

You dont say what Model Llimited) engine ( 6? 8? )or Manual or Auto temp control. but maybe check the ground wire for the blower. G200 black wire, which ends up under console. check the black wire at the motor, if it has voltage on it, the ground is bad. the power wire should have 12V
