Air conditioning problem

could be several reasons. could be a fuse, a bad belt, no Freon, or a loose wire on the compressor or a leaking Freon hose. IF you hear the compressor kick on when you turn on the ac, but have no cold air, don't continue to run it because the compressor uses Freon as a lubricant also. Take it to an ac shop.

check for compressor clutch operation, if the clutch is engageing you could have a bad compressor or a blockage in expansion valve

if it WAS working then gradually just seemed to not get cold it sounds like freon is low. with the compressor cycling on-off it has some freon in it. just add a small amount. i'll be honest its best to have someone with the recycler machine do this it will save you from adding too much and possibly damaging the compressor. most shops have a freon service special around 99 bucks?

If the freon is at the correct level and your AC compressor is teh most likely candidate. Have the AC compressor checked.

The compressor on the air conditioner in my 2000 GMC Yukon XL went out last summer. Had it and the whole line replaced at a local air conditioning shop last fall. Used it little before cold weather. Warm weather this spring and no cold air. We could hear the compressor trying to kick in. The shop told us that the control console was bad and had to be replaced. They told us the part was on back order and did not know if they would be abel to get one any time soon. We took the Yukon into the local GM dealership. They told us that the high side fitting was bad and that the freon was very low and that they would have to deal with that first to check the system. Called back to the air conditioning shop and they said they had a console come in and they would put it in and check the high side fitting. I now have cold air and questions. Bought Yukon in 2005 used, had always had problem of not switching to cold air once the heater has been used. We were told changing the console should fix that. It has not changed. I feel like the console angle was a scam, that the system was just low on freon. Each shop was blaming the other for trying to scam me. And what can fix the heat to cold issue? If anyone has answers I would sure appreciate the knowledge.

high pressure switch is kicking out on overload, replace it or you might have too much freon

Check the A.C>Relay or It could be low or leaking freon

not a home mechanic job thats for sure ,check youre pollen filter isnt choked up if thats ok then you need a specialist repairer because the venturi offrice is blocked which means that the high pressure gas isnt going through the small hole causing it to stay hot.must ge er indoors moaning

Most likely a loss of refrigerant ( freon ) in the system. The A/C compressor uses a low pressure switch as a SAFETY to insure it wont turn on without freon in the system. Hope this helps.

1st Thing,
Located Someone With a Set Of A/C Gauges 134A Freon,
Make Sure Your A/C System Has Enought Freon In It, There Is a Low Freon Pressure Switch
In The Electrical System, Usually, 50-60 PSIG or Less On The Gauges, Will Indicate Low Freon, When Freon Is Low The Compressor Is Dis-engaged To Prevent Compressor Damage.
1] Low Freon
2] Bad Low Pressure switch
3] Blowen Fuse[s]
4] Electrical Problem[s]
[a] Digital Climate Controlled ?
Climate Control Self Diagnose From Button's On Unit, OEM Manual Explains This,
If Yor Auto Has Digital Climate Control.
5] Bad Compressor DC Coil

Note: Does The Compressor Engage, Click-On When Button Is Pressed, But Getting
Only Warm Air?
Is One Of The Compressor Aluminum Tube's Cold, Be Careful Other Is Really Warm/Hot,
If Cold and or Sweating, Dripping Water [Normal], You Are Blending Hot Air w/Cold
Air At The Heater Blend Box, Making Warm Air.
If This Is So, If A Vaccum Controlled Temp Unit, Check For A Vaccum Hose Bad,
Should Be Either 1or 2 Vaccum Lines Going Into Firewall To Feed The Controller
Unit, If OK, Might Be a Bad Blend Box Diaphram, [Control's A/C air, Blocks Off
heater Coil Hot Air].
If Your Auto Is Vaccum Controlled, Can You Changed From Bottom, Dash,
Defrost Air Flow?, Yes, No Vaccum Lost Feeding Controller, Still Might Have
Bad Diaphram Blending Hot Air w/Cold If Your Have Cold Alum-Tubing In
engine Compartment.
If Digital Climate Controlled, Might have Diaphram's, Vaccum Controlled or
electrical Servo's Controlled vs Diaphram [Vaccum] Controlled.
This Might Help, Hopefully, This Is Just For Starter's, There More To Some System's
and Without The OEM Mgr's Manual[s] You/Be Would Be Lost, especially w/Electrical.
Later, God Bless
