Most likely the same problem i HAD...I decided to do the job myself.. Very time consuming but do-able. When you get a chance and decide to change the heater core yourself, make sure you arrange everything in the same manner it came out of the truck. If you dont have an aftermarket alarm, you'll probably save yourself much more time than i did. I have to cut and label 22 strands of wire before i could get the dash out...
Once you get the dash board out, the tricky part has yet to come.. You'll have to squeeze your hands down in the engine compartment to disconnect the heater core hoses and the a/c lines..heres an FYI..THERE'S A RETAINING SCREW ON THE FIREWALL THAT IS CONNECTED TO THE HVAC ASSEMBLY..MAKE SURE YOU REMOVE IT.. it sets on the firewall just to the left of and behind the throttle body... you will rack you brain trying to figure out why it wont come out until you unscrew it..
If you have any questions, just reach out.. i'll try to guide you through it
