Mine has always done this. As far as I can tell it is just Engaging in anticipation of a Person wanting to change the Temp. Computer Signals it to do this.

In my 2000 ford expedition my temp gauge keep jumping back and fourth when I run my ac. Y?


Running the AC does increase load on the engine, and thus heating, so if gauge changes gradually, this is because the compressor kicks in for a while, then kicks out. If cooling system is not working properly, small additional load could cause temp change. Other possibility is compressor going bad and causing excess drag.

If change is sudden, loose wire somewhere near compressor could be the issue.

Tip

Climate control settings,on all vehicles


When using the ac on a hot summer day,or a mild spring day,the compressor runs all the time.If you set it to low,and turn the temp to cold or toward the warmer side,lets say cool,then the ac compressor runs also,it just cycles,on,and off.No matter what setting you are using on your ac control,the ac compressor stays on,using fuel.Get the most out of your ac,while it uses your fuel,to keep you comfortable.All vehicles have a MAX setting,or a recirculate setting.Always use this setting.I say,always use this setting,not only that,but use this setting.I stress this because you are pulling in air ,from the out side,that is warming the evaporator,and making the ac work harder to give you comfort.In the hot ,hot summer,the settings MAX,and recirculate,keep the air that is in the vehicle,in the vehicle.It recirculates the air,instead of bringing hot air inside the vehicle ,and bringing the temp,up,to a warmer temp.A lot of people don`t even know that this is on the control,or don`t know what it is for.Some times the recirculate button,or dial,will have a picture that looks like a C,but squared off at the corners.So folks,get more out of your vehicles cooling and heat system.Yes ,this will work on heat also,maybe not defrost,but on some cars,it will work.

I have a 1996 audi a4 quatro and have replace the climate control. all the buttons work and lights up but the ac compressor does not kick in and the fresh air door wont close. reinstalled old one, dampers...


I have a 96 cabriolet, and the AC controls are cable operated. Check your cables under the dash. there i a button for the ac, right next to the recirculate button separate from the dials. If that doesn't kick in your AC, check relays and fuses, and then low pressure switch, assuming you already know that you are full of freon.

Our 2001 V70 -AC shuts off during driving and wont come back on until car is stopped turned off and restarted, you can hear compressor kick on but wont stay on regardless of temp control setting.


The A/C needs to be serviced by a certified volvo tech or some one who know's a/c very well it can be just low charge or the speed sensor on the compressor.

The ac is blowing hot air the freon charge is good but the ac still blows hot air whats the problem with my 2000 chevy silverado?


Is the compressor kicking on? If not and the pressure is in the normal range then I would say that the low pressure switch is stuck. It is located on the canister right beside of where you hook up the freon. Unplug it and cross out the plug and see if it starts then.

If your vehicle is equipped with automatic climate control, this should help.

Recirculation Operation
The HVAC control module controls the air intake through the recirculation actuator. The recirculation switch closes the recirculation door in order to circulate the air within the vehicle. The outside air switch opens the recirculation door in order to route outside air into the vehicle. Regardless of the blower motor switch position, recirculation is available only in the panel and bi-level mode switch positions. Including the OFF position. The mode switch must be placed in either the panel or bi-level position before the blower motor switch is placed in the OFF position. In order to reduce windshield fogging, outside air is circulated when the mode switch is in the defrost or defog positions. If the recirculation switch is pressed into the ON position when the mode switch is in an unavailable mode position, then the recirculation switch LED will flash 3 times. If the HVAC control module detects a fault with the recirc door the HVAC control module will try to drive the actuator for a predetermined amount of time, to outside air, which is the defaulted position for the recirculation actuator

Ac compressor won't kick on


Just had the same issue and posted. Just found the solution is the control module in the dash. Went to the junk yard since new is expensive on these units. Plugged new unit in, was able to charge a/c now blows cold as ice.
