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.

SOURCE: 95 dodge dakota heater blower not working

It has been a long time since I've replaced one of those. From what I remember you don't have to go through pulling the heater box out. You do need to remove the glove box assembly. Look up under the passenger side of the dash. If you see the bulge of the motor/cover hanging straight down then remove the cover and the motor will be there. If you don't see that then te motor is mounted horizonally. If that is the case then the fresh air door assembly will need to be removed and it is behind that.
Here is a quick check to see if the motor is bad. Thump the bottom of the heater box by the passenger's feet. if the motor comes alive or makes noise then it is bad. Also check the fuse and make sure that it doesn't work on any speed. (the resistor would prevent operation on only one speed or more but generally not all speeds)

I have a 2005 dodge grand caravan and the radiator fluid was coming out by my feet


If it was coming out by your feet while you were inside the van, your heater core is leaking. Replacing the heater core is a big job - requires removal of the dash assembly.

1987 dodge van, my heater does not work


If the blower isn't working check the fuse/circuit breaker, and relay if one is used. If the blower is working, and if in the defrost mode warm air is produced then it is likely a problem with a vacuum actuator that diverts airflow in the duct system. Some vehicles have a valve that controls hot engine coolant flow to the heater core, if your vehicle has one it will be located where the heater hoses pass through the firewall check to make sure it is functioning correctly.

How do i replace heater core


I believe on a 1987 chevy van the heater core should be under the black plastic cover on the firewall on the left hand side as you are standing in front of the van.
I believe you can also get to it under the passenger side dash.
It is NOT fun. Unless you are a seasoned mechanic, I would not attempt it.
Otherwise stop by your local auto center, and get a HAYNES manual, they will be able to show how to.

When heater is on i smell coolant


Hi

This is caused by a leak in either the heater core itself or the hoses connecting to the heater core.

Rust and corrosion can clog the tiny passages in your heater core. Sometimes the block becomes so severe that pressure builds up in the heater core causing it to spring a leak of coolant - enough to give off the smell you describe.

You can find examples of the heater core at this link
http://www.autopartswarehouse.com/shop_parts/heater_core/dodge/ram_50.html

Solution: Replace heater core or hoses depending on what you find.

Hope this helps. Please do rate this answer. Many Thanks.
