Okay, I'm at a loss. I have built several C4s, and I can do alot with my eyes closed. But I know there is someone who knows more. I cannot find the lcation of the blower motor relay on an '87. I need to know the factory location for both types of HVAC, manual and ACC.the factory service manual does not tell the location under the dash. Neither does Chiltons, Haynes, etc...
Also:
*the fuses are good: the 5a fuse at the blower and the IP A/C fuse.
*the blower motor is new and not bad
*the ACC display shows no fault codes
*the system wiring is all good
I feel like a moron for not remembering, but I'm getting old. Please help!

You mention the 5A fuse, and that is only present on the C68, so I looked that up in a 88 Helms manual.
I find mention of a Blower Control Module. Located: "Front of dash, in LH side of evaporator housing".
The wiring diagram does not show a "relay". Only this module that has a power input from a fuse link (red), ground (blk), output to motor (purple), and control from Control Head (brn).
