1997 Ford Explorer Heat and AC Stopped working at the same time?

4.0L 4x4 Eddie Bauer Eddition 1997 Ford Explorer. My AC & Heater stopped working same time? Coincdence or not? Don't know where to start, i'm thinking relay switch to start, Help…

There are only two things that are common to both the A/C and heat… The switch and the blower so first things I'd check are the blower relay and the switch, That's assuming you've already checked the fuses.

Sounds like the switch to me…
check it out then go on to resistors and fuses etc…
