High Blower Only Due to Failed Blower Motor Resistor on Dodge Ram Van 2500

Problem Description and Possible Solution

The HVAC blower may operate on high speed only. This is commonly caused by a failed blower motor resistor. Chrysler has released a revised part to address this problem.

Replaced blower motor resistor several times after twice losing all blower speeds except high, and then only after losing the middle speed. New resistors last less than a year before they fail. If there is a revised resistor who is the manufacturer and what is the part number I need to stock up.
Soved problem here. Heat fan worked only in high setting. I changed the resistor that is under connected to the heater casing (a big black plastic cover) that is located on you the left side when you open the hood. It surprise me that is quite small, I removed the two screws and took it to the local auto parts. When I changed the first one didnt work. I bought a second one from a different brand and too it didnt work. I was thinking to go to the dealer and get an original, but I decided to check carefully the cable and the connections and indeed I found that one of the connectors was very slightly and unnotizable burned, moved and pushed those cables while I had the heater on the middle possition and kept trying until it finally worked. Now I will change that connector tomorrow and will retun one of the resistors. Dont forget to check the both fuses from your glove compartment and the hood. Indicated locations are on the drivers manual.
This is my 4th Dodge Cargo Van from 1982-2000. all have had this issue.

Blower only works on high. replaced blower motor resistor and it worked for only about 8 months. I noticed the connector to the resistor is melted on one end.
We noticed the blower would only work on high and it would also run when the key was in the off position. I changed the AC/heater control. That fixed it for a short while. The fan is only working on high again.
