I need a wiring diagram for a 1999 Jeep Grand Cherokee

The stereo was taken from the vehicle, at which point all heat and air controls were pulled out. Since vehicle is going to be used as a rock-crawler, I would like to run heat and air from switches etc.. I need a Wiring Diagram Showing which wires are for the heat and air conditioning.

    paul erickson May 11, 2010 claims they have factory repair manuals, they have nothing of the sort, this is not to say some experts may have manuals, we do, but we work from home and in most cases have a small library. Experts are not employed by, we help free of charge as much as we can with the general automotive knowledge we have learned while working as auto technicians, specific test values, repair procedures and illustrations are unique to each car line, these are not in most cases available to us. Thanks for using FixYa!

Usually you have to splice the wires into the old plug.
You might be able to find a diagram on the websites for auto parts stores such as autozone.

1999 jeep grand cherokee air blows but not out of vents, also tempurature seems to not work...any ideas

most are controlled by vaccuum lines, check your lines running from your engine thru your firewall, and make sure that you have vacuum at the line where it passes thru, if you dont, you have a line off or burnt in two in the engine compartment, if you have vacuum there, check where it connects into your heater controll underneath the dash, i've had them pull loose when installing stereos or doing other things under the dash,

1995 Grand Jeep Cherokee

The lower speeds are controlled by a resistor block. That's what needs to be replace. It's usually located next to the blower. It will have electrical wires connected to it. High speed bypasses the block so it alway works.
If you want to replace it then;
) Disconnect the battery negative terminal if the vehicle have air bags. Wait 2 minutes for system to discharge.
) Remove the kick block on the passenger side. )Remve the glove box ) Remove the bolts holding the blower motor resistor. Push the red lock up and press down on the click ) Pull the block out. ) Install new block and reverse steps above.
