Re: air conditionor dos not drain
You will find it on the passenger side on the fire wall to the bottom you'll see a short hose sticking out with a soft wire push it through and be careful not to pock a whole the evaporator. if this information has been useful please let us know good luck

1. First you have to disconnect the Oldsmobile vehicle battery, then you have to drain the engine coolant into a clean container, most models don't have a drain plug on the bottom of the radiator, so you must take off the lower radiator hose to drain the system.
2. Second you have to remove the drain tube from the heater's housing and disconnect the heater hoses from the core, to reach out the heat core you have to take off the sound insulators on both sides of the car, then the steering column's opening filler and finally the air outlet duct and the floor air outlet.
3. Third you have to disconnect the heater core cover and then remove the core-to-housing mounting clamps and remove the heater core.
4. Fourth you have to Install the new heater core and connect the mountain clamps. I did a quick online search and if you need new Heater
Core this site looks like it has cheap prices, free shipping and great
5. Fifth Replace all the core cover,rear floor air outlet, air outlet duct, steering column opening filler, sound insulators and center console (if equipped). Reattach the heater hoses to the core and the drain tube to the housing and fill the cooling system, using new coolant if the old liquid doesn't appear clean. Be sure the lower radiator hose is securely back in place before filling the radiator. Reconnect the negative battery cable.
drain coolant system locate heater cores hoses going through firewall you need to buy the radiator flush kit at any auto parts stores. remove heater cores hoses from one end or buy extra long heater hoses same size as heater core hoses in vechicle at auto parts store use the flush kit when you flush through one of the heater core hoses let the other hose drain in a drain pan when you use home garden hose use low water pressure dont use garden hose to the max or you will rupture heater core. your best bet let radiator shop flush whole coolant system. because heater cores hoses are in a tight spot.make sure engine off if you just going to flush out heater core only .after flushing heater core good time to replace heater core hoses.if job too hard or complicated let radiator shop flush out radiator the engine block and heater core because if radiator stopped up or engine block stopped up the gunk and rust will reenter plug up heater core.if you tight on money you can flush out your own radiator.drain out radiator using large drain pan. remove top radiator hose and remove bottom radiator hoses connect to water pump.use garden hose with flush kit part with water pressure not too high put garden hose to top radiator hose run water until clear water run out bottom radiator hose in drain pan,the flush out engine block remove thermostat.if you had another spare thermostat housing with RTV SILICONE SEALANT THAT HAS SET UP INSTALL THERMOSTAT HOUSING BACK TO ENGINE WITHOUT THERMOSTAT FLUSH OUT THE ENGINE BLOCK, WHEN DONE INSTALL NEW THERMOSTAT THEN INSTALL ORIGINAL THERMOSTAT HOUSING WITH NEW ORING WHICH YOU BUY AT DEALERSHIP.IF ALL SOUND COMPLICATED LET RADIATOR SHOP FLUSH OUT COOLANT SYSTEM.
Sounds like you may have water leaking out of your heater core.
This will cause an overheat condition, which you get because your engine cooling system can't pressure up as well.
You may also notice a kind of "sweet" smell to the air that comes from the air vents that blow when A/C or heater is on.
As water leaks into the A/C & Heater core compartment area...it trickles to the overflow drainhose on the firewall. This is usually intended for the condensation of the A/C core but a leaking heater core will drain that way too.
From what I hear, I'd see about disconnecting the heater core hoses going into the firewall and maybe use a splice to connect them to each other OR get a two 5/8 bolts and a couple clamps and plug the hoses.
This allows you to drive car without overheating and buys some time to get you another heater core (basically a "mini-radiator") Its summer, so you don't need the heater right now but keep in mind...you won't have a heater until the core gets replaced.
Replacing the heater core in a Pontiac Sunfire is a very difficult and complex process. The heater core is kept within the car's heating/air conditioning module behind the instrument panel. So many other parts have to be drained and removed from the car
to reach the heating/air conditioning unit that you may be better off
leaving this to a professional mechanic--especially one licensed to work
on air conditioning units. Things You'll Need:
Air conditioning reclaimer
Hose clamp pliers
Recharge service hose
Removing the Core
Make sure the car is cool, the front wheels are facing
forward and the ignition switch is off. Drain the engine coolant by
removing the drain plug at the radiator and letting the coolant pour
into a clean container, then do the same at the engine block's drain
plug. Recover the refrigerant by connecting an air conditioning
reclaimer to the system high and low side fittings as its instructions
Disconnect the evaporator lines to the evaporator by
removing its bolt and disconnect the heater hoses from the core by
loosening the hose clamps with clamp pliers. Remove the drain tube from
the evaporator case. Disconnect the negative battery cable.
Remove all the trim covers and panels from the
instrument panel; some of these are screwed on and some require a flat
bladed tool. Remove all air distribution ducts from the panel, the air
bags, the steering wheel, the radio, the tilt and washer levers and all
electrical connectors, then unscrew and remove the instrument panel from
the car. Unbolt the cross vehicle beam, remove its wiring harness and remove the beam.
Remove the air outlet in the floor. Disconnect the
wiring harness for the heater/air conditioner and the electrical
connectors at the blower's motor and resistor.
Remove the heater/air conditioning module by removing
its attaching bolts and the assembly screw. Remove the heater cover case
by removing its heat stakes and screws and remove the heater core.
Install the replacement core into the heater/air
conditioner module, then re-connect the heater core cover case. Install
the assembly in the vehicle,
aligning the mounting bracket to the front of the dash slot and
mounting bolt hole. Reconnect the electrical connectors and wiring
harness and install the floor air outlet.
Reinstall the cross vehicle beam and every component of the instrument panel. Reconnect the negative battery cable.
Install the drain tube back on the evaporator case. Connect the hater hoses and the evaporator lines.
Recharge the air conditioner. Connect a can of R134a
refrigerant to the air conditioner's low side service fitting with a
recharge service hose and a high pressure gauge to the high side
fitting. Open the service hose valve while the car runs with the A/C at
the max and let the vapor flow until the gauge reads between 225 and 250
Refill the cooling system at the radiator filler neck. Use fresh coolant if the old liquid is dirty in any way
common problem is the water resivor cracks up at the bottom... it appears that your water level is fine because the car doesnt over heat but i am willing to bet that resivor doesnt have water to the top. The radiator will hold just enough water to keep it cool. I replaced mine 3 times the sulution is doing to sound weird but go to the junk yard and get one off a murcury sable. dont know why but the sables res doesnt crack like that
The drain hose does not actually exist. The evaporator box (also holds the heater core) is partially in the engine compartment and partially in the cab on the passenger side and excess water from running the AC drains immediately into a frame member. This is a unibody vehicle. There is no way to access the end of the drain tube to clean it out. The drain hose runs through the firewall and into the frameThere is no way to get to it from the outside of the vehicle. The only way to relly reach it, is to remove the housing. Sounds absurd,but that's the frantic truth about this car.. Good luck.
Three possibilities--the windshield is leaking water, the heater core is leaking antifreeze (should smell like antifreeze), or the air conditioner evaporator (near the heater core) has a plugged drain tube and the water condensed out of the warm air is running back into the cab. Hope this helps!
It sounds to me if you are having a "musty smell" then you might have a problem with your condensation drain line for you a/c system or a small leak on your heater core. If it is plugged then water will collect in the vent system causing a musty smell from the water not draining and if there is a small leak on the heater core then coolant can collect in the vent system. I would run the a/c on a warm day and look for water draining from the vehicle around where the dash is located to check the drain line. As far as your air cabin filter most are located behind the glove box. You usually need to remove the glove box to get to the filter.
Typicaly only a few items that can cause this. your thermosat needs to be replaced. But unless it's really cold were you are right now. I would say not what you need. 2. Heater valve or vac line going to it need to be replaced. This valve is a plastick valve that you will find in line with your heater hose that goes to the heater core. Normally found near the firewall. 3. The heater core itself can get pluged. If get the car warmed up and then turn on the heater you can place your hands on the heater hoses right were they go into the fire wall. If one is hot and the other not, you have bad heater core. Also a good way to check the hater valve. The good thing is all items except the heater core are easy to change.
