First of all, thank you so much for the response and help!The likely culprit for your settings not displaying is the A/C Auto Amp, which is a separate box attached to the back of the display. It's unlikely the AV Unit is responsible since your other display and radio functions work. The Auto Amp has its own fuse, #8 in the cabin fusebox, so make sure that's good. If the Auto Amp is bad or offline, it's possible that's causing the blower to run all the time, so I'd address that before assuming the VBC (resistor) is bad.
If the VBC is bad, don't sweat the number of fins on the replacement. Different manufacturers use different heat sinks, but it won't affect operation. Your existing one doesn't appear to be OE, so someone probably changed it one or more times already. When they melt short-circuit it's almost always because the blower motor is sucking too much startup current, so if that's the case, you should replace both the motor and VBC.
Does the A/C auto amp look like the pics below? I guess it’s the same thing as the “temperature control module” since that is also what the sellers are calling it. I found this one on eBay but I’m not sure if it’s the right part. Also, you mentioned that it’s unlikely the AV unit is responsible since my “other display and radio functions work” but I just want to clarify…the radio screen comes on but NONE of the buttons for the radio or climate control work currently work. I can’t change stations, I can’t change the temperature of the air coming out of the vents, etc. It’s weird to me that the radio and climate systems are connected like that but oh well. I’m not sure about buying a used replacement for it but short of going to a dealer and paying a fortune this is mostly what comes up online.
For the VBC I’m glad it doesn’t really matter if I replace it with one with the 4 fins. I never know with this vehicle what parts actually go to it or not sometimes from some of the things I’ve come across. I’ll try the A/C auto amp first and hopefully that fixes my main issue.
Thanks again for the info. It just seems so difficult to find a straight answer for certain issues like this.
