Blower speeds.....

[Ronin1082]

Sure I'm beating that horse, sorry. I have ripped my dash apart numerous times between installing the HU, two was radio and wires for the subs. In that time I might have done something cause the Lowest speed on the blower doesn't work any more.

Suggestions where I should start? I don't plan on taking that dash apart again till I do the LEDs.

likely the heater resistor is bad.

im not sure exactly where it is on that year, but it will be somewhere in the heater box.

you should see the plug directly into the box. the resistor protrudes into the box itself.
this resistor is what you gives you the different fan speeds.

Is yours a limited?

I would almost bet money that one of the coils in the blower motor resistor has split over time; that's exactly what happened to mine. Was the very first repair I did; OEM part was like $22, and the install took me 15 minutes ONLY because I did it @ night with a flashlight in my mouth. LOL

The blower motor resistor is located below the glove compartment; all you have to do is remove the glove compartment itself (easy to see how if you peek up under it - just remove the screws securing it to the black bar), unplug the wire harness, undo the screws holding the resistor in, then pull it out, and I almost guarantee it'll be cracked.

Then reverse the process with a new one.
