Hi all... Long time lurker, but can't find the right answer so hoping to get some help diagnosing the following issue:

-- Heather blows even when car is off
-- Climate control unit is dead - no lights
-- I pulled the blower motor resistor and replaced it with a napa parts version - problem still exists (returned the part)
-- All glovebox fuses look ok

I replaced the resistor but left it unplugged for now.

Thanks for your help!

After FSU (what you call the blower motor resistor), the IHKA (climate control) module is the usual suspect.

You're lucky Napa let you return that resistor! They usually don't let you use the parts to trouble shoot like that.
