Need HVAC Wiring Diagram for 97 SE w/Auto Climate Control
Hi, My 97 Bonneville SE doesn't blow any heat and it's starting to get cold in New Hampshire.
So far, I verified that the blower motor works when connected directly to 12VDC.
Also, I installed a new Blower Control Module under the hood (in the firewall) and a new Heater Core.
To troubleshoot further, I need a wiring diagram that shows the connection between these units:
Automatic Climate AC & Heater Control (ACDelco 16220102)
AC Climate Control HVAC Programmer (ACDelco 16218972)
HVAC Heater Blend Door Actuator (ACDelco 15-71835)
HVAC Blower Control Module (ACDelco 15-8684)
HVAC Blower Motor (ACDelco 158542)
Does anyone have this wiring diagram or know where I can download a copy?
I greatly appreciate any help. Thanks!

My digital GM service manual only goes back to 1998, so things might be a little different, but this should get you on the right track.

Re: Need HVAC Wiring Diagram for 97 SE w/Auto Climate Contro
Thank You greatly for the wiring diagrams! They're just what I needed.
I'll check online to see if my HVAC modules are the same as for a 98 Bonneville.
If so, then your diagrams should work perfectly for me.
