95 Jeep Cherokee
ac was working fine. needed to route some radio
wire so i unscrewed the ac controller in the dash.
there wasn't enough slack in the wires so i
disconnected 4 wires behind the fan speed control
and a big black connector from the middle top of
the controller. after reconnecting everything the ac
only blows out the defrost vent. i know this is
symptomatic of a vacuum problem but i don't see
how what i did could cause a vacuum problem
when everything was working before. thanks for
any help.
