Hi - I'm new to this forum and this is my first post. I have 99 Grand Cherokee Limited with auto temp a/c feature. Got the intermittent 'fan works/fan doesn't work' problem. Finally died completely. I can hear the doors/dampers opening when I turn on the air. No blower sounds. Little bit of cold (or hot in winter) air comes from vents when vehicle is moving. Nothing when stopped.
I read the post at http://www.wjjeeps.com/blower_motor.htm
and decided to replace blower motor resistor first. The old resistor had 2 sets of wires coming from it: 1. 3-wire set that will be spliced into new plug provided with the wiring package and, 2. a 2-wire (red and black) connector (hard wired into the resistor) was dangling free - not plugged in anywhere.
Have spliced in the new wiring kit (3 green wires) to the new resistor, reinstalled the resistor, reconnected the battery -- and nothing is acting different. The hardwired red and black wire connector isn't plugged in yet anywhere -- Should it be? If so, to where? - thought I'd better ask before I replace more parts.
Sorry for the length - thanks for your replies -
