SOURCE: will a transmisson out of

you will have to check the size of the tranny, that will work with your vehicle. If it does, you may have to change bell housings. As long as the tranny is rated for your rear end and truck, you should have no problems, they do make adapters for mounts.

My 2005 Chrysler Town & Country 3.8 Liter AC is not blowing cold air. I would like to try recharging with one of the R-134 kits. Is the low pressure port that I would need to attach the R-134 canister...


the hose fitting that you attach to the low side port will only fit that port-it cannot fit the high side (that port is too big) so you cannot do this wrong. The low (suction) side is between the compressor and the evaporator (passenger compartment, usually in the heater core plenium.)

Want to add refrigerant. air conditioner not very cool. which is low pressure port for adding r134a coolant?


The newer cars have 2 ports. The large port which is the high side and small port, low side. The kit you buy to refill the air cond will fit only one of the ports and that's the small port. You don't want to hook up on the high side so, this is why ports are sized and the gauge will only fit one. The low side should be near the evaporator or on the evaporator.

Air will only blow on floor no matter where i set the dial and is only warm this is a 2005 trailblazer


May be the heater/AC control unit in the dash.The heat stays on the floor because the door actuater moter is not switching direction of air flow and as far as the warm air,if you engine is up to operating temp,then the heater control valve is not opening fully.Both are conected to the heater/AC control unit.

Replaced battery in 2004 chevy trailblazer 4x4 8cl., then air conditioner doesnt blow out the face vents only the defrost and feet. any ideas?


Typically, you have a vacuum issue, air flow system is designed to FAIL in the defrost mode, so no vacuum, doors are spring loaded to blow out defrost ports.

Temp gage goes to 260, air conditioner blows warm air. Replaced thermostat, still does it. Now What


WITH TEMP 260, CHECK ALL FUSE, AND RELAYS, CHECK ALL HOSE FOR CRACKS, CHECK THE RADIATOR FOR CRACKS, MAKE SURE THE HEAD GASKET IS NOT BLOWN, CHECK THE DIPSTICK FROM A OIL AND WATER MIXTURE.

Air conditioner


The one closest to your AC compressor... i.e. the part that the belt spins around.. Is the low side.. Not to mention, air conditioning recharge hoses ONLY FIT on the low side.. Worst case scenario, try both.. the one that it clamps down on to is the low side..
