Question about 2003 Jeep Liberty

2 Answers

My vent will only work when the nob is turned to 4. It doesn't blow air on 1, 2, or 3.

My car blows hot and cold temperatures, fan, defrost, and air work, but it will only work if the blower is on 4.

What has happened is the there is what is called a resistor pack that limits the current to the blower motor during the operation of low medium speeds the reason it still works on high is high speed dosent use the resistor pack to regulate the current you have 1. lost power to the resistor pack 2. lost ground on the resistor pack or 3 the resistor pack has failed. this would be a great place to start and is a very common problem again be sure you do have power and ground before replacing the resistor pack you could have some electrical problems

SOURCE: 1995 Jeep Grand Cherokee Climate Control issues

. Open the gloves compartment (gc) . remove 2 rubber pieces that keep the gc on its place (both sides) . look to the left side. there is a connector with a few thin colored hoses. This thin hoses are there to control the operation of the blend air door. It is vacuum operated. . now follow the thinnest hose, probably it is green, all the way to the right. It connects in a sort of vacuum valve that control the position of the blend air door. make sure it is firmly attached to it. also check that hoses connector to ensure that all thin hoses are well connected. . OK! start the motor and operate the knob on the panel. It should work fine now.

SOURCE: 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.

Vents won't blow hot or cold air. Comes from defrost and feet when you put fan on.


It's the vent actuator, it moves the baffle that changes the direction of the air flow.
Here is a video of a broken vacuum hose that creates the same problem.

It could also be a failed actuator.

My 2007 grand marqis only blows hot air from the defroster vents. will not blow any cold air. Need help before spending a lot of money taking out the dash.


If you have electronic automatic temperature control, press and hold off and floor buttons at the same time, with key in the on position, then release and press auto for 1 second.this will put system into self test. If numbers come up,152-52-32- 132-or some code, Google it..most likely the blend door actuator,some have found a way to do it without removing dash at s much lower cost.

I have a 93 4runner v6 manual. I went to turn the heater on the other day and no air was coming out of it but when I started driving down the freeway air started coming through the vents. When I stop


sounds like your fan is either jamned, burnt out or even frozen, you might be lucky and find its just a blown fuse, you'll need to check your fuses box then start investigating if the fan turns freely or not

if you put the air on recirc you might be able to stop cold air blowing in when you are travelling. if you are waiting for a garage to sort out the fault then get a fan powered by the cigarette lighter, air moving over the window should at least keep mist clear even if it doesnt defrost it

This car has the automatic temperature control system


The hot/cold switch is probably bad.you have a blend door box that opens to let the cold air in and closes to let the hot air in.From what you are saying this part is no responding to the switch movement.Make sure power is at the switch and power should go through the switch when put on cold air this moves the blend door.Some times the blend door goes bad and has to be replaced its under the dash on the right side.
