Are you talking about the air cooled rear seats?

I have that too if that's what you're referring to. I guess let's start w/ what's wrong w/ your HVAC system. Maybe people on here can help then.

Nothings wrong with the HVAC other than I may need to change the servo that controls the drivers side heat. I had a clogged up heater core which I flushed for hours some months ago with CLR. I think I need to flush it some more before it gets cold. My issue is that when I was doing the active tests for the hvac system and was increasing the fan speed. Each mode is supposed to max out at like 240 or something but none of them would go over 176. The troubleshooting chart said to change the amplifier so I was looking for an inexpensive one to test that theory.

Gotcha. I have the 88650-50440 that I can send you. Just send it back afterwards when you're done.

Thanks but I don't believe yours will work due to the fact that I have an L model with the rear seat upgrade and separate AC package. Cool box, reclining seats and audio controls....
