heater contol unit schematic WANTED

Post by TerryRuth » Tue Oct 09, 2018 12:08 pm



HAVE it torn apart and see by wiring diagram that HCU controls ALLL
any idea what
green/orange
red
yellow
black
yellow/ black
these are all on the 3 switches and all play with the hcu which I think grounds all the heaters I see the positive running to all ( so other side MUST be ground??) and will see if the switches are sending power also will see if continuity in all heaters
guesss I want to know which pins on the hcu plug in to run power on the plug to see if the switches are functioning my hcu is not grounding the relay for sure that MAY BE ALLLL the problem but want to check while I have it apart

Vcc = positive power reference
V GND = Ground

The variable resistors have Vcc at one end and ground at the other. The wiper arm travels anywhere between the Vcc end (which gives full power) and the ground end (which gives no power) to determine the setting.

The wiper arm output for the rear seat heater is RR HS (yellow wire).

The front seat heater wiper arm is FR HS (blue wire)

The grip heater wiper arm is GRIP HS (yellow/green wire)

VB is battery power coming from fuse 11.
