I just got a 2007 Infiniti M35. The gauges on the cluster and climate air don’t work. I found the AC amplifier module behind the climate buttons above the CD player toasted. I replaced it with a good used one, but as soon as I hooked it up it smoked.
Something is over loading that board burning the chip inside. All my fuses and relays are fine. The car starts and drives fine as well, it’s just that I have no AC no air and cluster gauges don’t work. I need to drive it to get it ready for smog and I can’t. I ordered three other AC amplifier module boxes but I don’t want to hook them up and burn them. What’s causing that circuit to overload? I have three fuse boxes by the passenger fender and battery all those check OK and the fuse box by driver foot checks OK as well. Fuses 10, 11, 12, 17, 18 are all good. What the hell is causing the AC amplifier module to over heat and burn? Only certain part of it, one capacitor is burning which is causing the issue with gauges and climate but the rest of the board is OK, because if I disconnect it and the car is running it over heats so it cuts off the fan and other lights turn on on dash, so I keep it connected because it does more than one job which is. Help please!
Note: the Cabin air filter seemed very, very dirty and had a big bend in the paper, so I replaced it with a new one. After reading about the blower motor in another post, I am gonna check the relay tomorrow and maybe I can jump the blower motor to make sure it's working. That sucker could be seized, causing my AC amplifier to fry as well, and cluster gauges not working.
Unbelievable if that would be the case. I would be so glad I came across that post, I will post follow up with what I find out for every body to read.
