55 degrees to 60 degrees
There should be at least a 12 degree split between the incomming air and the air comming out of the vents.
You need to pop your hood and check your vaccum lines should be by the passenger side should be little tubes and stuff with a TT piece maybe running by your engine or possibly into your firewall !! - Phat-Boi
Is the compressor running ?
The coil is dirty.Hose it out with a water hose.
There are 2 filters you access in the glove box. If they are dirty you get almost no air. Clean or replace them and be amazed at the difference
Any leather gloves are great for cold weather, and some have vents for when your hands get too hot.
no
There is no heater matrix for the back air vents, only and evaporator for the A/C. My suburban always blowed cold until I added an extra rear heater matrix.
The climate control is not operating for the passenger side. Check to insure the physical controls work, and the diverter vents are opening to let the cool air to the passenger side.
mine did the same thing i just added some coolant to it and it fixed it and havent had any more problems watch your hands though its the line running between the fan and the motor ... i walked around with burnt hands for a week
Cold air blowing out of the vents when the heat is on gas could be due to a few reasons. One common reason is that the furnace may need maintenance or repair, such as a clogged filter or a malfunctioning thermostat. Another possibility is that there may be a problem with the gas supply or ignition system. It is recommended to contact a professional HVAC technician to diagnose and fix the issue.
maybe the a/c needs to be recharged with freon
