You don't seem to get it

The DMM helps you find the source of the problem. Something that replacing parts hasn't done for you.

No. That makes no sense at all.

If you take the car to a mechanic, then I guarantee one of the first things he pulls out will be a DMM or test light. He'll print out an electrical schematic, and he'll start narrowing down the problem and eliminating possible causes.
If you don't want to do it the right way, and your methods failed, then maybe you should take it to a mechanic as Cusser suggested. Good luck.

 

how the plug look on the blower motor resistor? they can melt and not have a good contact

 

I do appreciate your time responding to my post, but i was actually hoping to find someone who has ran into the same issue and has experience with troubleshooting the problem and providing some feedback as to what the solution was for him or her to aid me in getting to a solution. So far you've said to get a DMM and troubleshoot, but if you don't have a schematic to provide to me and detailed steps as to what to probe where and what the expectations are then your feedback and commentary is useless. putting a test light on the circuit doesn't tell you if you've got the correct voltage or its pulling the correct current. it just indicates power so that's not very sound advice. in the future if you don't know the answer and can't help me get there just keep your comments to yourself. if you don't know the circuit and can't tell me based on what all I've replace where else i should be looking then you have no experience with this issue and thus once again your commentary is meaningless and useless so like mommy told you growing up, just keep your mouth shut.
anyone else out there actually run into this problem and get to a solution?

 

i replaced the control unit with the unit from my truck. it didn't solve the problem.

 

the plug on the blower motor resistor was fine, however it has since been replaced. i took the individual crimped wires from the stock connector and put them into the replacement unit. no melting or signs of overheating

 

Sounds like you already know everything, daddy wasn't around, and mommy didn't raise you with manners. Have fun.
