The pressure switch is stuck open, You can try unplugging it for a few minutes with the ac turned on to reset it,If that doesn't work it may need replaced.

Only blows heat when accelerating


the ac core only blows cold air but You must be talking about the heater core.. In which case I would suggest that you bleed the air out of the coolant system as there is an air lock in the heater core.

2003 Suzuki XL7 A/C won't stay on


The low pressure is in the grill by the radiator. The issue your having with it cutting off then on is easily fixed by removing some of the AC coolant. Any ideas on why the rear AC is not working? Is there a seperate fuse for the rear AC? It just blows warm air.

Nissan Altima no cool air blowing or hot air blowing


Hi!
It appears we have an Air lock scenario and you will need to perform a system Bleed.
Park the vehicle on level ground, when cold remove coolant filler cap, start engine and leave to idle, turn heater on full and blower to max. When engine reaches operating temperature watch and listen near coolant filler, keep clear as gurgling and hopefully a boil over should occur. Top up with very warm coolant and wait as it may do it again.
Check for heat inside vehicle if warm replace coolant cap but keep an eye on temperature gauge as the ~Air lock may have moved on from heater matrix/core so proceedure needs to be carried out again from COLD.

97 Ford Econoline air conditioning and vent settings blowing hot


I know from experience that if the coolant is to low ( not just the freon levels in the compresor but the antifreeze/coolant level as well) the AC system will not cool and will blow hot. Check the coolant Antifreeze and freon levels, even with the Coolant being a little low my 1998 Ford E150 Van will blow hot. After you have ruled out of these possibilities and the chance it is the thermostat most likely the problem is what Ford calls the "Flap" it controls the air flow through the vent system when you switch from Heat to AC. When the Flap is working it closes off one systems air flow so as to not interfere with the current climate selection.

Temperature Control not working on 1999 Ford Explorer


Sounds like your temperature actuator is not moving or your temp door is broken. On max a-c ,coolant is shut off to your heater core allowing only cold air in.
