If the line is bad, pull bad one and go to local parts store and get needed length. Actually, whenever I've had to go that deep, I replace all vacuum lines as they tend to get brittle and crack with age. Replacing all avoids failure down the line. And bulk vacuum line doesn't cost that much. You might consider replacing that T as well.

My 1999 limited does this. When i bought it off the guy he said that its because of some flap down by the passengers left foot. In mine the passenger air barely even blows because of this.

SOURCE: 1996 Jeep Grand Cherokee Laredo AC blower wont work on high

I'd check the relay and the resistor ...don't have a location for yours but the resistor is always installed into the heater box so it stays cool. you can usually follow the wiring back to the relay as it's generally nearby. Resistor looks like a piece of circuit board material with several wires connected to it with two screws holding it to the heater box so it sits flush except for the wires. It has several coils inside...any that are broken have failed.

2001 jeep grand cherokee larabo 40 vacumm line broke going thru fire wall looking for a fix that doesnt require removing the hole box

That would be the vacuum line going to the heater/AC control head, so you could pull out the HVAC controller, find the main vacuum line coming from the engine, and splice, with new connectors and new line as needed, the line back together.

A/C problem with 2000 Jeep Grand Cherokee Laredo

Check the vacuum line from the engine to the ac controller. There should be a one way valve that is bad. The other possibility is the vacuum canister is not holding enough vacuum.

2002 jeep laredo interior vents won't blow except

The mode control on your heater panel uses engine vacuum to operate the doors in the heater box. when the system loses vacuum, it defaults to the defrost setting. find the small plastic vacuum line that penetrates the firewall and leads to the engine intake manifold. Check the hose that attaches the line to the engine for cracking or looseness. If that is OK, trace the line back into the cabin. It should lead to the control panel. Check any tees or couplings for leakage. If it's good all the way to the mode control switch, it is likely the connection to the switch or the switch itself is leaking. With the engine running, listen carefully to the switch for hissing. It is also possible that the defrost door actuator is bad. If you can find the door, try applying vacuum directly to the actuator to see if it operates to shift the flow. If it doesn't, replace the actuator.

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,

Why does air only come out at windshield instead of vents on my 2000 jeep grand cherokee laredo

I had the same problem. The small vacuum line that goes thru the firewall, next to the AC lines, was broken. I fixed it with small piece of hose from the autopart store for 85 cents.

Sounds like a vacuum problem.Listen for hiss noise under hood and under dash. may have a bad vacuum diaphram that controls blend door or leaking vacuum line.

2001 Jeep Cherokee a/c blows defroster only, no cruise control

There is a vacuum leak under the hood somewhere. Check the vacuum at the speed control servo. If there is no vacuum on the line with the engine running, follow the line to find the leak. The vacuum reservoir is mounted under the battery tray. I would look in that area after confirming no vacuum at the servo.
