Allow me to make a recommendation. get a haynes manual. generally like 15 bucks at the local autoparts store. get an extra pair of hands and about 4 hours. there are a boat load of screws so make sure you bag them and label them. the heater core is located on the passenger side of the vehicle. once the dashboard and support behind it is out you ll have a casing in which the heater core is located. make sure you remove the negative from the battery terminal and all remove all pressure from the AC. remove the bolts for the AC tubes on the outside of the firewall as well as the two tubes that are attached to the the heater core (they are located in the same area).

MAJOR ADVICE take youre time. this will take about 4 hours to remove the dash, 10 minutes replace the core and another 4 hours to put it all back together. I am in the process of putting mine back together in case you have any questions email me. ricardo(dot)markland(at)gmail(dot)com

best of luck

1999 dodge 5,9 diesel warm heat only

First thing I would do is flush the heater core with a 4 to 1 mixture of water and muratic acid. Put it in there and blow it out both ways 3 or 4 times. Let the acid mix set for about 10 minutes before blowing it out with air. This is a cheap fix, if it works. $7 and your time. Got to say though, it only works about 30% of the time. The other 70% is to remove the heater core. Dodges/Chrysler su(k. To get to the heater core, you have to drop the steering column, and remove the entire dash. Then remove the heater/A/C plenum to remove the heater core. Buy a manual to do this. Way to many hidden screws and bolts. This job costs about $800 at a garage. It takes about 8 hours to do, if you know what your doing.

Have a 1999 limited edition jeep cherokee atomatic 4.0 liter 6cyclinder. doesnot have heat. need to know how to remove an replace step by step heater core

Typically a heater won't cause a no heat condition unless it's clogged. On these Jeeps, it will usually leak either inside or outside of the truck. The whole dashboard has to come out including the steering column in order to access the air box, which also has to come out in order to change it. If you are having a no heat issue, you may want to check a few things first. Make sure thermostat is working properly and installed correctly. Verify coolant level is good and no air pockets in cooling system. Make sure the blend door motors are working and switching from cold to hot. A good way to see if you have good flow through the heater core is to feel the heater hoses at the firewall where they connect, make sure they are both hot after engine is fully warmed up. If 1 is hot and the other is cold, you know the core is clogged. If that's the case, you can try disconnecting the hoses and back flushing the heater core to get any dibris out. Otherwise, you will need a book or manual for the procedure, it's very involved and time consuming.

Why is it blowing cold air all the time sometimes if i turn the power down it blows a little bit warm but not much

Hi, it sounds like you flow is restricted, probably due to clogging of the heater core. You can try back-flushing the core by removing the heater hoses on the engine side and attaching a garden hose to the lower heater core port using a bit of hose and some clamps. Run the hose to flush out the core. If flow is good, replace the hoses. If not, you may need a new core. Please let us know if you have more questions, and thanks for using FixYa.

I have a 4cyl 1999 Jeep Wrangler. The heater only blows warm air, no hot air. I have back flushed the heater core with a garden hose and there was no clog. I have checked the t-stat and it is...

The key is the heater hoses. The top hose is the inlet for the heater core and the bottom is the return line. If the bottom hose is not hot, there is little flow through the heater core. It does not have to be completely clogged to reduce the heat output. The core needs to be flushed multiple times IN BOTH DIRECTIONS through the heater hoses. If this does not restore the heat, try a commercial/radiator flush. Many people have had alot of success by filling the core, through the heater hoses, with a CLR type product and letting it sit for 10-15 minutes to remove scale followed by a thorough flush.

I dont know what these other guys are saying..I think they snif the glue!!! YOUR BLOWER FAN ASSEMBLY CAN EASILY BE REMOVED !!
1. Remove the wire
2.Find the "tab on the housing and pull it down while rotating the fan housing counter clockwise. This will remove the fan assembly. Plage 12 volts on the contacts to test the motor. If it works then the resister pack is blown. On the fan housing (near firewall ) you will see a plug going into a square looking box with a screw in it. Remove the wire then remove the screw to remove the resistor pack.. A new resistor pack is around 20 dollars at a ford dealer. Hope thie "FREE" info helps!

When driving, heater blows warm air. When idling, cold air.

check your anti-freeze level, I'd bet that you're a little bit low!

Blend door functions, why no heat? exactly where is heat core?

First, there are two doors inside the heater. one door changes air flow between heat and A/c, the other changes where air is going (vent, floor, defrost etc). You did not mention if when you moved the door by hand, if you got heat when you did that, or, if the motor you removed had vacuum going to it and if it was functioning when you moved the dash control. Next, you don't need to cut holes in the box to check the core. If the hoses going to and from the core are getting hot, likely you have flow going through it. You can do a temporary visual check by replacing one hose with a clear plastic one and observing flow. (don't leave plastic in place as it will get soft when hot and will eventually fail.). You either have a vacuum problem not allowing blend doors to move, a second door that is jammed, an obstruction, internal or external (leaves, mouse nest etc) of the heater core.
If yours has a heater control valve that is installed on the heater hoses, check that as well (failure default is usually full on which will normally give you heat, but they can stick in the wrong position as well).
Last, I know removing the box is a real pain. Generally though, in the end you will need to remove it if the core needs changing. I'd first attempt to flush the core, independently of the system by removing both hoses at the engine and draining the core, then filling it with flush, waiting a half hour or so and then blowing it out both ways with a garden hose.
