erikfl Posted May 10, 2010 Share Posted May 10, 2010 I have a 1999 GS 300 A few weeks ago the blower for the AC started having issues. The blower speed and output would take on a mind of it's own and blow at full speed then cycle to a slower speed then completely shut off (all while the control was set to maximum). Then after a few minutes it would turn back on and continue to cycle up and down. Some days it work fine, then the problem would repeat. Now for the past 2 days the blower does not turn on at all... I am not sure if it is the blower controller module, a relay or even if the blower itself has bitten the dust. Any suggestions would be appreciated.
