You relay switch is stuck on. Replace it. Second thing to check is the fan switch may need to be replaced. If you turn off your engine and then back on does the heater fan go on even when it is turned off at the switch?
The fan blower will work independently of the ac switch but the ac will not work unless the blower fan is switched on. It is possible that you have been using the one switch to control both with out realising what is going on.
SOUNDS LIKE THE SWITCH & OR THE BLOWER MOTOR RESISTOR, ARE THE PROBLEM WITH THE LOWER SPEEDS. SPEED 5 MAY HAVE ITS OWN FUSE, REFER TO OWNERS MANUAL FOR INFORMATION ABOUT THE HEATER/AC FUSE.
next to the fan motor there should be a connector that has three or four wires that attached to the blower resistor. it should have two screws holding it to heater case, just pull it out and replace.
there is no relay for the heater fan it's a 15 amp fuse and is on the accessories circuit. the reostat is responsible for all 3 speeds .with the key off there should be no voltage to the blower motor whether the fans speed fan switch is on or off. the fuse will be located in the fuse paneleither on the drivers left side in the dash or underneath the dash in the fuse block. you have a short in the harness that is under the dash and most likely it's a bad plug on the harness. your going to have to do some searching but that's where the problem short is... please rate
