SOURCE: When I turn on the

As far as the A/C goes. Does the A/C compressor turn on?? if so, than you may have a MODE door problem in the air box. Do all heater knobs turn freely or is one of the binding up?? I have seen the MODE door gears falling off and sticking the MODE door on hot setting. Test knobs for movement. If A/C compressor is not coming on, than you may have a leak and all freon leaked out or it could be just a simple thing like fuse or relay. Test to see if A/C compressor comes on. As far as the alarm goes, you need to switch your security from silent to non silent mode. Here is how its done. Hold BOTH lock and unlock buttoms together for about 5 seconds. (the directionals or sidelamps will flash)That will switch the alarmmode to NON SILENT and back to SILENT if you need to.

SOURCE: air conditioner not working properly

I have just ordered the part to fix this. It is the A/C vacuum actuator (not sure why they call it a vacuum actuator because it is an electric actuator). It is under the dash on the driver's side close to the radio. There are two in the same area. It is the one closest to the floor. You can verify by taking it out (pull out duct that runs from center of vehicle to the outside to get better access), and actuating the vent by hand with the blower on to see if you now get air out the middle vents.

The part number is 1573596 from Rock Auto on the net. It cost $40.79.

SOURCE: AIR CONDITIONER ISSUES... I NEED HELP

Most cabin filters are behind the glove box and require you to remove a stop screw to open the glove box completely to allow access to the filter....check your owners manual for exact replacment instructions. If the A/C is still not cooling well, purchase a can or R134a with a pressure guage at you local auto parts store and follow the directions on recharging the system. If you need to recharger it again later, have the system inspected for a leak.

My 2002 saturn sl1 is weakly blowing luke warm air out when i have my heat at its hottest setting and my fan at full blast.


the best way to find out if the problem is in the cabin or under the hood is to touch the heater hoses when the motor is at operating temperature. turn on the heat full blast and feel the hoses; if they are both almost too hot to touch then the problem is with your blend door or its control mechanism. if one is noticeably cooler than the other then you,ve got a clogged heater core. if they are both cool enough to touch then your motor is running too cool

A/c vents not working right


I would make sure you don't have the air blowing out on the floor setting and recirculating. Some vehicles pull air in from floor setting when you set them on recirculate and this causes obvious issues. Might also check your "cabin" air filter, this is different from the engine air filter. Most general repair manuals will tell u where it's located and your local car parts store might also be able to help you find your vehicle's filter location. Your blower fan might also be getting worn out but I would save that for your last check. If the air just isn't cold enough all the time u probably just need to recharge your freon. Hope this helps.

My 2004 lincoln ls air conditioner is blowing hot air. The ac filter light is on and so is the check engine light. Please help. What could be the problem? Does the system just need to be charged?


Your issues can not be answered easily or definitively, as the LS is very complex and all electronic.
I would need the stored codes,that set the check light (MIL Light)
You can cycle the right dash display to ACFilter and Reset,with the top row of buttons,in center of dash. There is no sensor on the Cabin Filter. All the dash displays, are just reminders,you can set any way you want, % wise.

Possible issues--Fuses
-- Coolant control valve
--DATC module

You will need a really good Technician,not a general mechanic, to diagnose your problem
You need to put a professional scanner on it, to start any diagnostic work

Heater and a/c problems


You may need to install a new cabin filter, most vehicles with A/C have a cabin filter to take out the airborne dirt.
Try switching to fresh air and see if you get more airflow then on return air.

Has enough freon but still blows hot air,whats wrong with my air?


First you need to make sure your testing you ac when the car is on. If its still blowing hot air make sure you have the ac setting set and not the fan setting. If thats not the problem make sure the compressor in the ac is running it give off this distinct humming sound when the ac is turned on, you might need to put your ear next to it if you can find it. If the compressor isn't working check the wiring in the car, and make sure the fuse/chip for the compressor are fine.
