Hi, you should start by checking your temperature suith at the cilinder head and the fan relay , those are the must comon for the problem you describe, ( be sure you chech all the fuses)GOOD LUCK......
SOURCE: blower speed
you need to replace the blower risistor. it should be located very close to the blower motor. it usually has 3 wires that are in a row and one wire a little to the left of it but located on the same oval fixture. go to the auto parts place and buy one . this way you will no exactly what it looks like so you do not have to spend a lot of time and money researching it.

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
