Question about 1997 Jeep Grand Cherokee
I don't know where the air blend door is
You need to drop the glove compartment and cut through the plastic that covers the blend doors e mail me at firstname.lastname@example.org and I will tell you how to do this its better than dropping the whole dash!

The Jeep Grand Cherokee sucks air from the outside via a hole on the passenger side of the cowl. It's under the black plastic piece that runs under the wipers.
The air is then sucked via the blower and blown into the housing where the heater core and A/C evaporator core live.
The blend door is inside this housing as well.
This also depends on if you have regular climate control or the more advanced ATC digital climate control found on some of the Limiteds.
You could possibly take out your glovebox and see if there are any broken pieces going to the door accuator.
Otherwise if it's internal, you'll need to take out the heater/ A/C housing.
To get to this housing, you have to take apart your entire dash, lift the top dash cover off, and then you'll see the housing. You could possibly check for a few thing there.
Most everything there is vacuum controlled.
You have to drain your antifreeze and have your A/C freon discharged (use a professional to capture the freon).
There are 5-6 nuts holding the housing to the firewall. You have to reach these from the engine compartment.
Disconnect your A/C lines and heater hoses. Pull out housing.
This is definately an advanced project, thus the reason for the high pricing.
Hopefully you can get it fixed without having to take this Jeep apart entirely. Try diagnosing with a vacuum gauge if necessary before tearing it apart.
