Question about 1997 Buick LeSabre
Typical issue, or so I thought. Automatic Climate control, Blower
motor starting blowing at high speed only and continued running when
car was shut off. Resistor issue of course. I replaced the Blower
motor control module with Advance part# RU1004. Full control of blower
was restored, but the A/C compressor does not engage. System is fully
charged and was working perfectly prior to blower issue. Fuses are all
good. I have not checked to see if there is voltage to the compressor,
my guess is no since it's not running. What am I missing here, could
there be a relay that is out, does the power module do more than power
the blower. Module I replaced was Delco part# 16173860
Appreciate some direction,
Disconect the negative battery cable from battery for 20 seconds and replace cable back,then try ac let me know if this helps u
