White smoke out of the tail pipe may be an indication of a bad head gasket in the engine. Pull your oil dipstick out and see if the oil looks a little milky.

air conditioning compressor clutch has failed Need new compressor assembly

Follow your gas line. I think it is in the tank. Have someone turn on your key on but don't start it and you will hear a noise if you put your head under the car by the tank. I think it is electronic.

your either going to have to take the pulley off or try to get around it some how if its the water pump pulley remove it.

that would be a dealer item new. you can find a used one at a junkyard or on ebay

Get a tiny drill bit - (1/16inch ) . Look over the light assembly and drill into the lowest point, making sure you drill only into the lens and not the housing. **** the bit around a little to remove plastic burrs - this should get the water out. You may want to check with your local wrecking yards for a replacement light assembly as yours has a crack, allowing the water in.The water will cause corrosion in the bulb socket, eventually forcing you to replace several bulbs before you'll have to replace the socket.

The air, after exiting from the heater, is diverted to the different output ports on the dash by some flaps. In your case the flap controlling the defroster ports is nonresponsive, stuck closed. The only way to find out why is to take out at least the center console and check the flaap itself (it might have been seized in by dirt) , it's lefer (it might be broken) or the control cable (it might be broken or unhooked).
If the fault is with the flap or the lever the entire dash will have to come out to allow for its replacement. In any case this is a big job, that you should leave to a repair shop - no need for a dealer, get the cheapest one you can find.

P0401--- the egr valve has insufficient air flow. Needs to be taken off and cleaned, if not replaced. The port holes might be clogged up, or the valve itself might be bad.
P0441---- The evaporative emission control purge valve has low air flow, probably do to the egr valve.
If you take off the egr valve, you will need to replace the gasket, or it won't seal right when it's put back on.

you probably have a loose conection or durty battery terminals
