Lot53yahoo.commy jeep x 2005 a/c blows out the defrost ,did work fine then just went bad . i cant find the actuator loc or is it a vac leak ??

You've got a vac leak...somewhere.
Unfortunately, you'll have to make time to find it.
When you lose enough vacuum...the "blend door's" default position is to blow out the defrost.

I've looked for vac leaks with starting fluid, or Barryman B12.
While engine is running spray hose connections...when engine "surges"...that's where the leak is.

Hope this helps...

Theres no tension behind the gas petal when i press it

The pedal is connected to a wire cable which runs to a valve or flap of some type at the intake end of the fuel injector under the hood. Either the cable has broken, or the spring which keeps the fuel injector opening closed down to idle position has broken or the cable has come off at one end or the other. Raise the hood and have a companion move the pedal up and down while you find the accelerator cable housing, most likely will be black. If the stiff wire cable inside the housing is moving with your friend's movement of the pedal then you should look to the end of the cable. You will see a small grooved wheel and the cable lies in that groove, and its movement turns the wheel which moves the flap inside. If the cable is not moving then your accelerator cable has broken or come loose at the pedal end.

I get air only thru the defroster, none onthe floor,

Usually a broken vacuum line will do this.The hvac system is designed to revert to defrost to keep the windows clear.Look for a broken or vacuum that might have come off.Hope this helps.

Air condition vents on dash are not blowing any air, only the defrost vents on top of dash are blowing, any ideas

It sounds like the flap that controls air flow is stuck. It is controlled by vacuum. The vacuum line could be leaking, the line could be off, or the vacuum actuator could be faulty. Hope this helped.

Jeep AC blows cold air at defrost and feet but not through vents

There is a flap that directs the air. the flap is controlled by a vacuum actuator. This is located inside the venting. The actuator is connected to little vacuum hoses that attach to the temperature control switch. Either the flap is stuck, or the actuator has gone bad.

The air selector for the heater/air conditioner moves but the air only comes out of the defroster. I need to know how to remove the console to see if the connector is broken. Can anyone help?

under the dashboard just above the gas pedal is the actuator rod to divert airflow from defrost to floor and vents. This may have come detached. move the wire/rod until it can be re-attached on the diverter door and wire-tie it on.

There is a flap in your heater box that is controled by your vent switch by your heater controls. listen for a vacuum leak. that is common and hopfully the problem. there is vacuum lines that control the vent door that redirects the air to your vents.

Has your dash been messed with recently? if so i would check there first. you should hear a hissing if thats the problem.

Otherwise these also are common for that door flap to break and not switch NE more. thats the only 2 things that i can think of off th wtop of my head to be the problem. this would require the whole dash to come apart if its this problem

2006 Wrangler AC problem

You have a broken vacuum line to the dash panel control.
Look under the hood on the pass. side next to the firewall.
You will see some vacuum lines, maybe one came off?
