I have the same problem(been driving this way for 2 years). My water temp runs about 160, so I thought the thermostat might be the problem also. Hoping it isn't the heater core. Been freezing in the winter, but can't bring myself to spend big $$ to fix.

Your heater core on your dakota may not have a retaining valve so your constantly changing your coolant thru every part of your cooling system. Where your coolant lines go into the firewall check the top line for a retaining valve if you have one try tightening it, if completly tighten by replacement. That was my problem. Good luck!

I had this same problem for two years. Heat punp was OK, thermostate was OK, heater core OK....... the problem was fixed back flushing the heater core ......... very easy, you can do it your self using a garden hose . My Dokota has good heat now.

I had this problem with my 88 Dakota for years and finally pulled out the heater core, after unsuccessful thermostat changes and flushings. The problem is the design of the core. It is a thin, little cost savings attempt by Chrysler for a heater core. The aftermarket core was a wider honeycomb style, that us older guys are use to. I could cook myself out of there now, even with the windows open.

I have everythign pulled apart on my 97 dakota to replace the heater core. I bought an aftermarket one and in order for me to fit it in i have to break off the little tab that holds the old heater core in place as the new one is thicker. Does this cause any problems, noise, loss of heat??
Any help would be greatful.
Thanks

Sounds like you need to back flush the heater core.

A mechanic friend told me that my problem may be in the heat/ac control and vacume that should open and close the heat door. Any advice,,,, when I do operate the knob there is no sound from the heat door moving.

if you've done all that i would guess that the fins on your water pump are gone. check your hoses and see if they get hot. not warm but hot. if they don't then your pumps probably bad.

My dakota only has defrost which doesnt defrost, i switch between floor arms and deforst still only comes out defrost vents, even when i turn it off it leaves a residue on my windsheild that leaves me blind in the dark when passing other cars headlights and i can smell a heat type smell at all times but only from the driver side, was told it was heater core at first but a mechnic (over the phone) said it could be a vaccum leak, not tryin to get raped by a mechanic for somethin i could possibaly fix myself any suggetions or help would be nice before winter hits

I have a 97 Dakota,no heat, have flow thru the heater core and it's not leaking, changed hoses and thermostat and gave it the back flush treatment, still no heat. The gate sounds like its opening and can only get mildly warm air. Having good water flow and the hoses are really hot should tell me the core is ok right? What am I over looking?
