Another good use for these parts manuals is to give the correct factory name for apart. This aids greatly with asking the counter person at the parts counter to do a search. And the exploded diagrams really kick ass.

A bump to the top for a couple new members on the forums who have 78's.

Bringing this back to the top as I was searching for the manual this morning for a part number and diagram. A wealth of info in this manual.

awesome info. found my heater blower motor resistor 4114 599, as listed. however mine says 4114 (which the last four is almost unseen) 599 478. could mine possibly be frankensteined from somewhere else?

What are the first seven numbers on the resistor you have now, and is the 478 after the first seven numbers?

4114599 and the 478 is after the first 7. could that be a lot number? i got the new old one in the mail yesterday and it has 356 rather than 478. i really have no experience with this...as if you cant tell.

As long as the first seven numbers match, you should be good, does the new resistor look like the old one. I suspect the last 3 digits are a production code, not sure. I have a Mopar Parts Catalog that explains a lot of the numbers and coding.

looks exactly like the original. i installed it and the motor turned thru all settings but i am still not getting full force of air. getting ready to remove the motor and see what i find. i did find leaves in the rubber tube that goes from the duct work to the bottom of the motor. it was pretty full. might just go ahead and change motor. i saw where it has been replaced before. the red wire does go to power and the dark to ground.my other thought was that maybe the foam that connects the various connections might be a problem. i did find some that literally fell to pieces when i touched it but i thought that the defrost setting would not make much difference in the flow to the defrost. i would expect the other settings to be low with finding the foam gaskets (?) in pieces that connect to the dash board. so i will check the motor and the ductwork it sits in, check for leave blockage in the cage the motor sits in. irritating. thought this would fix it with the replacement resistor. guess i have multiple issues here. maybe the squirrel cage came off the motor....just a thought. hey, thanks for all your comments. its almost camping time and i want to get it going.
