GMC Repair: 1985 Buick Riviera Heater, buick riviera, good heat

Question
Hi!!
Just found this site... very cool!!  The fan is not blowing warm air.  When I start up the car and touch the heat square (digital?) the little light is on.  After about 30 seconds or so it starts flashing.  Do you know what are the possible things this little light flashing means?  I searched the owners manual and didn't find anything.  Thanks you!!
