Changing heater core and need to now how for 1992 K1500 series 4x4 pickup

im pretty sure u have to pull the whole dashboard out to change the heater core in that vehicle

It sounds like your heater core is stopped up. try flushing it out, you can use a water hose. and if you cant get it to clean out then you will need to change the heater core.

yea the blend door motor is bad it does not have a heater control valve

Sounds like either a plugged heater core or a baffle inside the heat box is stuck

unfortunately the fastest easiest way is usualy to remove the entire dash and its about a 2 day job

My 1992 gmc pickup keeps blowing heater fuses I have replaced blower motor can you help me jody.

first you have to remove the complete dash . recover the refrigerent for the a/c. I would advise replacing the heater core AND the evaporator at the same time. Dodge trucks are very common for both and you dont want to do the core and then a few months later the same job over again.

According to what I've read, a code 12 on your vehicle is the "all clear" code. I haven't found any information to indicate otherwise. What was said is that if you had a pair of fail codes, for example - let's use 15 and 34 for argument's sake - when you scanned the computer, you'd see 15, 34, 12, and then they'd repeat. The 12 was an indicator at that point that you had seen all the codes that were stored, and that they would now begin to repeat. If you have no codes stored, you'd see 12 and that's it.
