I have a 1998 ford explorer xlt the air will not change from defrost and floor to face. i believe there are some kind of flaps that arent opening when i turn the switch. how can i fix this problem?

I believe the problems sounds like a stuck "blend door" in the heating and air system. On most models, it's a dealer item at a cost around a $1000. Some self help repair may be available.

2005 chevy truck a/c works cant get heat blows cold

This sounds like a valve problem, or a heater/ cool air door stuck.
Many GM vehicles, have under the hood, a valve, it is electronic or vacuum controlled. When you switch the lever to heat, this valve opens, thus letting hot water flow through to the heater core.
On some newer models, there is a door (flap so to speak) within the interior compartment. This flap opens and closes between heater core and interior, thus controlling hot air flow.
Have you check to insure there is sufficient coolant in the system?
Low coolant levels will also cause no heat, but will also show signs of engine running warmer, sometimes much warmer than it should.
The valve under hood was as used on my 1995 Astro van. the mechanism looked to work as you could see shaft move in and out, problem was the diaphram or flap in valve on end of shaft (inside valve and not visible) was detached.
The other method, interior door or flab within heater box assembly was a problem on my 1998 Ford Expedition.
Yours, being GM, I would check for this valve under hood. It will be somewhat obvious in most cases as it will have heater tubes running into it and from it into firewall.

AC blowing heat and air at same time

Yeah Ron, the flap that covers the heater core is open and when you're moving the air is pushed over the heater core and into the cab your in. Possibly just a vacuum line of that controls said flap. Check all vacuum lines for good proper connection to these flaps because all of them are vacuum actuated.
