98 Explorer XLT 2-WD AC not working.

Wife called this AM, AC has stopped blowing completely on the truck. Matter of fact nothing is blowing, heater, defroster, everything. Think it’s a belt?

The research I’ve done says if the refrigerant is low the compressor will not engage for the AC. But I wouldn’t think that would affect the heater or the defroster.

Any input would be greatly appreciated!

If the fan isn't blowing, the refrigerant charge has nothing to do with it. I'd check the fuse, relay and the motor.

Re: 98 Explorer XLT 2-WD AC not working.

Thank you for the repsonse CatSkinner. I worked on it over the weekend. Did the following and still no luck.

1) Checked the fuses.
2) Checked the relays.
3) Checked the blower, it's fine.
4) Replaced the Blower Motor Resistor.

The research I did led me to believe it might be the Blower Motor Resistor. Reason being it was only working on the MAX/AC setting for the last couple of months before it finally crapped out on me. Think it may be a switch in the dash?

Check for power at the blower motor. One lead should have power and the other ground with it turned on. Here's the diagram.

Could very well be, I'm not sure which switch they used in the Explorer, but the one they put in the vans and trucks were known to have issues.
