Ignition Switch problems of the 2008 Dodge Ram 2500

The air conditioner/heater blower in my truck has been working intermittently, but getting worse to the point that it rarely works now. I took it to a shop a few weeks ago, but the system happened to work that day and they could not find any issues. However, I did some research on the internet and there are many other owners having this problem. The cause is a faulty ignition switch/wiring harness connector which actually melts from the heat caused by improper wire gauge/design. This information can be readily found on Dodge truck forums by doing a google search. There was a previous recall for this issue on earlier model years (safety recall #875 according to one site) but none that I could find for my model year. This is a safety issue as visibility could be reduced by frost or fogging of the windshield since the windshield defroster will not work. Moreover, failure of the vehicle's heater could be a safety issue in very cold weather--especially in remote locations. It may also be possible for the overheated/melted connectors/components to cause a fire or to manifest other failures associated with the ignition switch (uncommanded engine cutoff, etc. ). Thank you in advance for investigating this issue.
