My Daymaker LED Headlight does not work when it is cold outside but will work when the air gets warmer. The LED spotlights always work.
SOURCE: Yukon A/C, rear blows cold, front ducts a LOT warmer.
There is only one A/C system split into 2 zones. Check the blend door actuator, it may have failed in one position or something may be jamming it. Also check the control panel in the dash, My 98 yukon did the same thing, no matter what temp you selected for the front it would blow at about 70 degrees. There is a circuit board in the control panel that gets corroded and one of the circuits controls blend door operations. Have a look.
SOURCE: back air blows cold air, the front blows warmer air
I recenly had the same problem on my 1999 suburban, even after I replaced the whole ac system.
The heater valve, which is under the air filter area was not closing, causing heat to be blowing over the evaporator core. I used a zip tie to keep it in the closed position, and ac went from 70 degrees to 40. I think the vacuum switch is bad, 40 dollars (dealer part). You can also pull the vacuum hose off the switch, which is on the firewall and connect it dirctly to valve and it closes the valve, but fits loosley. Use silicone around vac hose if you go this route.
SOURCE: A/C air sometimes cold, sometimes not on VW Beetle 2001 Turbo
AC will not work with temps are cold even when it is turned on. The air is colder cause the temp is colder. The AC cycles in hot weather because the AC charge is low and needs recharging. You will know this if you open the hood run the AC and you will hear the clicking sound of the AC compressor magnetic clutch. You can recharge it easily buy buying a compatible can of refrigerant. I suggest buying the kit with the gage so you don't overcharge the system which will cause freeze ups
SOURCE: air conditioner works sometimes, sometimes does
chech your relays and fuses for the ac cooling system on the fuse box, then check ac compressor
SOURCE: AC unit outside blowing out cold air, vents
If you have a heat pump probably there's a wrong connectionin the thermostat, but if is not a heat pump ,the compresor is not working or the unit leaked all the refrigerant.
Testimonial: "thank you, we have had a problem in the past with refrigerant leaking, was supposed to be fixed"
