I had the same problem with my '03 Limited, but then the driver's side quit working as well. After further internet investigations, I learned that it is usually the heater core, located deep under the dash. To do the work yourself would take a lot of mechanical skill, and a lot of time. I took mine to the dealership, and they gave me an estimate of $1300. The steering column and the entire dash have to be removed. I have been driving to work in Colorado all winter without a heater. Just be thankful that it still works on the driver's side.
It must be a Jeep thing because I had the same problem with my 2001 Jeep Grand Cherokee. My boyfriend picked up a heater core for about 200 dollars and put it in himself. He's no mechanic so I don't think its that hard if your willing to put a little effort into it. Plus you save about 1100 dollars!
Passenger side under the dash board. That big black box which routes all of the air to the vents has to be removed.
The Vents Are operated by vaccum.. I found a cracked vacuum line on the inner fender under the hood alondside the battery that was cracked. the vacuum line runs from the firewalll to a reserve canister located under the passenger headlight. as soon as the leak was plugged the vents were working again.
Either you need to pen your vents or there is some vent obstruction.
Does blower motor run?
I have the same problem with my 97 jeep. I'm thinking that maybe a hose going to the vents has come loose, because I can hear the fan motor running and I'm getting a small amount of air out the vents in the dashboard area.
The heater coil probably has a leak causing steam and vaporized antifreeze to be released into the vents. Is it using coolant?
It doesn't have one. There is a useless screen under the cowl on the passenger side (where the hood and windshield meet). It is supposed to keep leaves and junk out, but it doesn't. This is why the drains clog so often on these vehicles and you get smelly mold coming out of the air vents.
i believe the heater core is leaking, a small pin hole leak can generate a lot of smell.
Could the heater door actuator be bad? What is the cost to replace? This Grand Prix has a dual-zone climate control and when the AC is on, the passenger side vents often change to heat when the control is still on cold.
Check for vacuum leak either under the hood or under the dash Check the operation of the vacuum actuators Check the selector switch Defrost is the default setting on this system
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.
Check behind the passenger side headlight between the headlight and battery for vacuum line leak! That is where mine was little rubber hose and it worked again
This happened to mine every year for 4 years. First few times it was a hose to the compressor, last time it was the actual compressor that had to be replaced...bought it on Ebay for around $300
You have antifreeze leaking from somewhere that is hitting something hot and turning it to steam.When you turn on the AC the fan is pulling it into the vents. Keep track of your engine collant levels and if they are lowering then there is your problem!!
you need to replace the vacuum.
93 grand am... that's a Pontiac product. Burn it!
To remove the air vents on a 2004 Pontiac Grand Am GT, a person will have to pry them out with a screwdriver. Apply gentle pressure between the vent and the dash.
Open a mobile snow cone shop in the summer? More likely you just want to stay warm in the winter. Check heatertreater.net for diagnostic information and a fix.
I happen to own one of these. I happen to also have the owners manuel. It is the fuse box located at the passenger side door. Just open the door, and you will see the fuse panel just below the dash. It is next to the hole that feeds the defroster through to the door vents. Open the panel and you will see the fuses. It is #26 and is a large silver fuse. It is a 30 amp.
Check for a vacuum leak either under hood or under dash Check the operation of the vacuum operated motors under dash Check the operation of the selector switch
my 2000 Chevy venture van the air comes hot by drivers vet and cool by passenger vents
your blend door which cost about $1000-1500
Antifreeze will be leaking in the floorboard on the passenger side, there will be a smell of antifreeze through the vents.
Most likely this is a blocked drain hose from the HVAC system. When it can't drip out condensation fast enough, the water contacts the AC evaporator and causes a foggy mist.
Probably not smoke. Your heater core may have a small leak and the "smoke you see is actually steam.Had a similar problem with an F-250 P/U. Cost about $100.00 parts and labor. But that was back in the day...
