I was in a small bumper accident and now I can not get cold air from my air conditioner. Where is it in the engine compartment and what would fail with a jolt like that?

Take out all the clips on the top of the bumper in the eninge compartment, the there are four bolts in each fender well, then eight bolts on the bottom of the bumper. Slightly pull on the side of the bumper and it'll come right off, I just recently had to do this for the same reason.

There are 2 ports, a high pressure and low pressure port. Both are in the engine compartment. I would suggest you get someone who knows air conditioners to do the work. This can be dangerous since Freon is extremely cold and can cause burns (freezer burns). Also you can damage your air conditioning system, and then it will cost big bucks to repair.

That noise is the electric air pump the location is not in the engine compartment but in the front under the bumper this only operate for 1 minute on cold start the purpose is to warm up the catalytic convertor this is a emission device.If the car is already warmed up and you turn off the vehicle and restart it wont come on.Its only for cold start ups.

Check the fuse panel.

there a restor on the front frame rail on the drivers side that gos bad it behind the bumper

-- locate where the air conditioner blower box is attached to the passenger side of the firewall – see photo #1 – look to the immediate right at the top of the gas pedal arm

-- condensation flows toward the front of the vehicle through the firewall at the leftmost edge of the air conditioner blower box – drain channel
-- open the hood and stand next to the front wheel on the driver's side
-- look down at the firewall over the battery and to the passenger side of the brake master cylinder – see photo #2

-- locate the small diameter metal tubes running horizontally and attached to the engine compartment firewall
-- locate the hole in the engine compartment firewall panel behind the small diameter metal tubes
-- this hole leads to the drain opening in the air conditioner blower box mounted in the passenger compartment
-- follow the brake tubes as they run from under the vehicle and turn toward the front wheel on the driver's side
-- locate the hole in the engine compartment panel behind the brake tubes
-- insert a short length of stiff wire into the hole through the engine compartment panel to unblock the drain hole

Your kidding,right! Check your vacuum hose inside the engine compartment, in may have a leak or come loose where it connects to the firewall. This may be keeping your air mixing damper from operating properly.

Three possibilities;
All related to blown fuses,

1- Fuse blown in the engine compartment LH.
2- Fuse blown in the cabin forward LH below the dashboard (below your legs left hand).
3- Fuse blown in the harness (wire bundles) below the dashboard very easy to reach with your hands “just look underneath steering wheel ".

U said " The air conditioner blows, but the air is not cold.
" Yes only the fan working which might receiving power independent all from those other mentioned things.
If all fuses OK. Then look for broken wires.

I agree with timmyb187. The dealership will test for codes and see exactly what sensor might be putting that light on. Under the bumper are sensors for the airbag. There could be a harness that got cut because of the accident.

If compressor isn't kicking in, check the connector atop the a/c accumulator, beside the coolant recover tank, in the engine compartment. That connector is atop a black bottle, and the connector goes to the low pressure switch. These switches do fail, and you can jump a wire across the connector terminals to see if the compressor comes on (engine running). As this circuit provides part of the ground path from the compressor clutch, if the switch is open, the compressor will never turn on. If the switch is failed, it can be replaced without opening the a/c system. Just disconnect the connector, unscrew the switch, replace it, and reconnect the connector.
