I also have problem with the fan turning on in my 1997 Oldsmobile Regency. I have heat but the fan only works once in a while. Do I need to replace the blower motor or is it something else.

I have the same problem , i was told that i would need to replace the ignition modulator ,cost about 216.00 bucks more then the beast is worth.

I have not replaced it yet ,also thinking about bypassing this problem with

a manual switch under the dash.

would appreciate input

My '98 Intrigue's low speed heater fan gave up a year ago :( Oh well.

Two day's ago the blower continued to run even with the keys out of the ignition!! Drained my battery :( I pulled the fuse & charged the battery. The engine now starts fine and after reinstalling the fuse the fan ran on its 2 high speeds. Then only on one High speed, then not at all. :) :) The fuse is fine. I disassembled the switch. It appears to function. However, there is power to the switch even with the fuse pulled!! But no fan. I heard no abnormal fan noises i.e. squeeks, squeles, hums or buzzes etc. My '98 Intrigue's low speed heater fan gave up a year ago :( Oh well.
