SOURCE: 1987 Buick LeSabre is idling too fast

Check for vacuum leaks. I find mine with spray carbureter cleaner. Engine will speed up when leak is found. Check the hose from the cruise control to the three way tee. The black tee turns grey and falls apart resulting in a vacuum leak. Should be on drivers side firewall.

SOURCE: 1994 Buick Lesabre blower runs on all speeds

If you are referring to the AC blower, you may want to check on the fan switch. It could be caused by bad contacts or loose connections. There is also a resistor if you would trace the wiring of the switch to the evaporator under the dash. Check if it is still intact. It may be partially be burned.
