I have Acura rl heat and ac

No online clues, I'm sorry. Your "hook a hot wire to it" statement kind of concerns me since you're not aware of what components do what and what goes where -- no wiring diagram, schematic, workshop manual to direct you. Therefore, you can't really deduce anything from what you've discovered -- only that testing needs to be performed. My concern is that you have any heat or cool air -- so is it maybe a temperature control issue? www.repairpal.com/repair-shops
