Could be one of blower motor relays contacts stuck closed . There are two blower motor relays 1 & 2 . One is located in the under hood fuse/relay box .
Or if your explore has automatic HVAC , it could be the front blower motor speed controller , this have been known to do this .
Which HVAC does your explorer have , manual or electronic automatic control.
You have fuses and relays . The fuses are or should br labled inside each cover if still there as well as on the fuse block itself, If not I can look under the hood of mine and tell you. The relays from left to right thats passenger to driver and numbered including the empty spaces as mine hase three on the right and two on the left with three emty slots in between. Now Olds seems to have kept this araingement for some time also my '98 88 has ABS as part of TCS but no relays there and diferent climate controls over the years it is posible you have more or less than are presnt on mine the complete list is as follows
#1 - AC compressor control for the compressors clutch
#2 - Horn relay
#3 - AC blower fan motor on, at low speed on the '98
#4 - AC blower motor off or high speed depending on year, not present on my "98
#5 - ABS pump relay ,not present on my '98
#6 - ABS Main relay also labled as pump relay for some years, not present on '98
#7 - High speed cooling or radiator fan
#8 - Low speed cooling or radiator fan
The most common cause of this is that the blower motor speed dropping resistor is defective, I suggest you try that first. It is located in the air ducting (the connector harness sticking out) near the blower motor. See picture below.
There is a fuse,but have you checked the blower motor?If the fuse is good,then bump the blower motor with you r hand with it on,see if it will try and come on,if it does,then the blower motor is bad,then check the blower relay.If this was at all helpful,please rate.The fuses are under the hood in the relay/fuse box on drivers side,and there are some on the inside,fuses.
There is a fuse box inside the car to the left of the steering column. fuse 228 10 amp and fuse 208 40 amp. Check power to the blower motor connector. Check for water in blower. I have seen water get into blower motor and short out. Good luck I hope this helps.
Ok, first off, check the fuses under the dash. If they're all good, does the blower work only on high speed? If yes, then you have a bad blower motor resistor, which is located under the hood, near the blower motor itself. If the motor doesnt work at all at any fan speed, make sure the wiring harness that plugs into the motor under the hood is clean and tightly installed. If it still doesnt operate, sometimes tapping on the blower motor housing will kick it on, but if that doesnt work, you may have to replace the blower motor. They are available aftermarket, and arent usually too expensive.
