Alright guys I'm going to replace the body control module for my AC blower motor. I was sure it was behind the fuse block on the passenger side, but it's No. 1 not 2. Now I know for sure the blower motor relay and couple of other things run off this fuse panel. How do I know body ecu no. 2 runs my blower motor? Well I got a wiring diagram https://www.dropbox.com/s/mxlcfsyoem5bu1s/Lexus 1999 GS400 GS300 Electrical Wiring Diagram (EWD356U).zip?dl=0&file_subpath=%2FLexus+1999+GS400+GS300+Electrical+Wiring+Diagram+(EWD356U)%2FAUTOMATIC+AIR+CONDITIONING.pdf. So either this diagram has a typo and the ecu behind the fuse block is number 2 or its somewhere else. If anybody knows where please let me know.
