Heater core is located under the dash board, as Jenkins said you need to remove the dash board amd all other panel to access it, you will have to spend at least 2 hours to remove them if you're not familiar with it, becareful not to break plastic locks and tabs. Get your self a service manual for your car and it will be a great help.

first off, disconnect your battery for at least 30 min before touching any plugs or harnesses. next, bleed your A/C and disconnect the quick connects that go inside the firewall. drain your coolant, and disconnect hoses from firewall. note a certain bolt with nut on it that is going to the inside of the firewall, you'll need to take that off when you get to the airbox inside the truck which houses your heater core. next, take off the pillar handles next to the windshield, then pop off the plastic dash panel with defroster vents. there are a few bolts up there that need to be taken out all the way across. next, take off your glove box. remove plastic below the drink carrier. there are 2 bolts there on left and right once you remove the plastic. there's a yellow or red AirBag plug which you may or may not need to disconnect later. next, drop down the whole steering wheel column. 4 bolts I believe. look up under there on both sides, you will see a 2inch piece of tubing that goes from each side of the truck. your dash and everything you see in front of you is connected to that tube. find on each side of the truck where that tube is mounted to the body with brackets. There are 2-3 bolts on each side I think. When you get those out, and the steering wheel is sitting in the seat or on the floor, the whole dash and panel should tilt and lay on the seats. there are wires from your a/c controls and radio which you'll have to disconnect and some various other wires as well. I also think you'll have to disconnect a harness plug with bolt in it on the drivers side. (white) after you've done all that and don't have the dash and panel in a bind with wire hangups you can now get to the air box. I don't remember how many bolts, but don't forget the one in the engine bay going to it also. get the box unbolted, then roll it up, remove 2 clips holding the heater core in, replace heater core and do this whole process backwards. Hopefully you didn't lose any screws or bolts. charge your a/c, replace coolant, make sure all plugs are connected before connecting power. Should save you $400-$500 in labor.

It's a big job. Drain the coolant down, recover the freon in the ac system and disconnect the lines and heater hoses. Lower the steering column, remove the instrument panel assembly, remove the heater housing. Split the case halves on the housing and there you are. Usually around 500 to 700 dollars at a dealership.

How to replace heater core in 2012 dodge avenger


Lotta work - need to remove dashboard to get to heater core - and before disconnecting heater core hoses you have to remove all coolant from car by draining radiator and opening heater valve to full heat. Remove core, replace with new one and reverse other operations. Make sure to properly refill radiator so there are no air pockets that will restrict coolant flow.

To replace 98 dodge avenger heater core, does the entire dash have to be removed?


Yes the dash has to be removed.... But I wouldn't give up up on a flush. I use muriatic acid 1 part to four parts water.let it set five minutes. blow it out. Do it again, the blow it out the other way. I do it 3 or 4 times. Watch what comes out. Takes about an hour and $6 for acid. Removing the dash is an6 hour job. If you know what you're doing....A week if you are doing it the first time and it is cold outside... Count on it.

Heater Not Working Correctly


I have the same problem with my Dodge Avenger. The issue is with the heater core. The company that made the heater cores for Dodge that year put to much flux in it. The flux comes loose and you get a sludge build up in the heater core that drops to the bottom of it. The heat for the passenger side blows on the bottom of the heater core. So that is why the air is cool on that side. Solution: you can try flushing the the system. If you take the cap off the coolant reservoir you will see the sludge build up. It has a reddish tint to it. Hope this helps.

Where is the flasher relay located on a 1998 dodge avenger


The flasher on the avenger is mounted in the dash under and behind the heater controls. You will need to remove the panel under the heater controls to access.
This is a combination flasher that controls both signals and hazards.
