There is a vacuum leak under the hood. On the 4.0 liter it is usually at the intake manifold near the brake booster. The 90 degree vacuum fitting pops off of the nipple of the intake. On the 5.2 liter the vacuum leak is usually near the battery where acid corrodes through the line as it passes near the battery box to the reservoir under the box.

2005 ford focus mk1 A/C button not working Compressor works since Cold air comes from defroster and heating vents in both sides of the dashboard


A/C Switch Assembly
The A/C switch assembly integrates the A/C request button, RECIRC request button and rear DEFOG button into a single assembly.
The A/C request button is enabled by the blower motor switch. The A/C switch assembly sends a reference signal to the blower motor switch. When the reference signal is grounded (blower motor switch turned ON) the A/C request button is enabled. The A/C request button is disabled when the blower motor switch is in the OFF position. When the A/C request button is activated (indicator ON), an A/C request signal is sent to the PCM. The A/C request button indicator can be toggled on and off when in the FLOOR/DEFROST or DEFROST mode, but an A/C request signal will be sent to the PCM regardless of the indicator status.
When the RECIRC request button is activated (indicator ON), the air inlet mode door actuator will drive to the recirculated air inlet position. When the RECIRC request button is deactivated (indicator OFF), the air inlet mode door actuator will drive to the fresh air inlet position. The RECIRC request button is disabled when in the FLOOR/DEFROST or DEFROST mode.

Hello from cold Kentucky.
The system uses a fan switch, resistor, and probably a high blower relay.
In the high position, the switch powers a relay that powers the blower motor. Any lower speed goes thru the resistor.
The resistor is on the firewall or under the dash depending on if the truck has air cond.
You can look up a blower resistor on the auto parts websites to get a visual.

check your blower hoses to see if one or more have come loose or got redirected or the selector switch isn't functioning properly (is it blowing better on defrost as opposed to floor vents, or forward vents, etc.)
Good luck

OK. So the blower notor isn't operating. Do you have power to the blower motor? The resistor is new from what I got. If you don't have power to the blower motor, then check the speed control switch and fuses. If you have power at the blower motor, replace the blower motor

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.

Defrost fan quit working.


Check it with a test light or Multimeter for power to blower motor first, with switch on high. If no power to motor, problem is elsewhere. Here's a link that will help you. Click on the pictures to expand.
