sonjaab Posted March 10, 2021 Report Share Posted March 10, 2021 (edited) Hey all! My 93 Deville is having a intermittent fuel center and climate control going dark. They will reappear if I shut off car, open and close door (to reset the light timer) and restart car. I note the fender guide lights also dont work along with the key and lights on chimes. Fuses ok, swapped relays and maxi fuses around also. Body Control Module dying?

sonjaab Posted March 27, 2021 Author Report Share Posted March 27, 2021 UPDATE: Had to go to the local pic a part yard for a glovebox light switch, grab bar covers and for $11 bucks a BCM for my Deville and a alt. for my s-10. Since I have read posts on the fuel and climate controls going dark and inop., no chimes I figured I would replace the BCM. I just left the old BCM in place, removed plugs then plugged in new unit and let it rest in glovebox hole to test. EVERYTHING works! Display, chimes etc! Will leave the new BCM that way for a couple days to make sure the problem is solved then reassemble correctly.

sonjaab Posted March 28, 2021 Author Report Share Posted March 28, 2021 (edited) Yea, $11 bucks and got me the glovebox lite n pushbutton, handle covers, trunk release button, a few relays and those big fuses under the hood. Got a shiny new alt. for my s-10 all for $44 bucks. FDC and CCC , chimes, etc all working. New BCM just plugged in and sittin' in glovebox hole till I am sure it works then I can re-assemble. Just glad I could disconnect the BCM wires and hook up new unit to see if it cured the problem. BTW: New/used alt. cured my s-10s intermittant no charge issues also! NOW I can head to Fla. and soak up some sun for a week or so and drive my girls POS Dodge Neon back to NY for the summer. (pray 4 me!)

sonjaab Posted August 27, 2021 Author Report Share Posted August 27, 2021 (edited) DAM! Think my $11 pic a part BCM has failed again! Fuel and climate displays are dark and no HVAC operation. I still have my old BCM and even tho the displays are dark the functions still work. So gonna pull the glovebox and plug in the old BCM and see if HVAC functions work and if so its off to the local PIP yard for another $11 BCM ! Maybe I should of bought the $75 reman BCM back then? The local PIC yard has 4 baby lacs so another BCM wont be hard to get. Its been 90+ daily here near Syracuse so need that cold breeze when ridin' dirty! My s-10 still has cold a/c so Im riding cool............ No fun drivin' her Neon car...........

sonjaab Posted September 23, 2021 Author Report Share Posted September 23, 2021 Back home and recd. the reman BCM. Swapped the chip. Plugged into car............ NO fuel or climate controls still! Gotta run the flo chart from serv. manual. \Any ideas? Quote 93 DeVille-13 Chevy Impala 72 GTO - 77 Triumph Bonneville 84 Z-28 Syracuse NY Link to comment Share on other sites More sharing options...
sonjaab Posted September 27, 2021 Author Report Share Posted September 27, 2021 (edited) Success! Replacing the Body Control Module didnt work. Manual states that orange/black stripe wire from BCM to the Climate CC and Fuel FDC should have 16 V at the FDC. Wire showed less than 5V at the FDC. Should of read 16v as the manual states. Unplug both CCC and FDC and the wire shows 16v again. Plug IN the FDC and the orange black stripe wire shows 16v. NOW plug in the CCC and both guages go dark and the wire shows 5v again. Well I guess the FDC unit has failed again! AGAIN: The $10 bucks I spent on the GM service manual was worth it! So I gotta look for another FDC controller! I DID install the $75 reman BCM cuz I cant return it.

rockfangd Posted September 29, 2021 Report Share Posted September 29, 2021 Good troubleshooting. You should have some... peace of mind replacing the BCM. Save the old one though. Good luck in finding the climate control module. There should be some still out there.

sonjaab Posted September 29, 2021 Author Report Share Posted September 29, 2021 Yea, There are plenty of them around used. Gotta head to a yard in Rochester to get one. Then I can put the dash back together. The tech who traced it out tore the dash to pieces!
