blower motor wiring 1990 YJ - JeepForum Sep 01, 2008hey guys im trying to get the wiring for my blower motor figured out. the heater blower motor went out and took some of the wiring with it. ive replaced the motor but the single wire that goes to the motor literally fell apart when i touched it, plus it was burnt as far back as i could see so im not sure what color it should be. so i would like to replace it all the way back to the source. butAuthor: SduncanHardtop wiring YJ Wrangler Defrost WiperNov 03, 2013YJ firewall wiring diagramMay 16, 2013HELP with Wiring 1990 Wrangler YJ.Dec 14, 2012See more results Jeep Wrangler Blower Motor Wiring Harness | OtoCars Order Jeep Wrangler Blower Motor Resistor Connector online today.
