2 fixes:

1. buy a PMD 6' cable extention and mount pmd inder your dash with a heat sync. on eBay.

2. buy a newly designed PMD like this on eBay http://cgi.ebay.com/ebaymotors/New-improved-PMD-6-5L-6-5-chevrolet-black-box-driver_W0QQcmdZViewItemQQ_trkparmsZ72Q3a1205Q7c66Q3a2Q7c65Q3a12Q7c39Q3a1Q7c240Q3a1308Q7c301Q3a1Q7c293Q3a1Q7c294Q3a50QQ_trksidZp3286Q2ec0Q2em14QQhashZitem330314039974QQitemZ330314039974QQptZMotorsQ5fCarQ5fTruckQ5fPartsQ5fAccessories
and this should be the last, especially if you do both 1 and 2

these US made PMDs have much higher rated diodes. The real culprit.

The blower motor location can change from year-to-year. It can also change with the trim level of the vehicle. A vehicle that has front and rear climate controls may be configured differently than a vehicle that has front controls only. The following are two different repair procedures. One is for blower motors located and accessed in the engine compartment, the other is for blower motors mounted inside the vehicle.

REMOVAL AND INSTALLATION

Engine Compartment Mounted

1. Disconnect the negative battery cable.
2. Remove the engine air cleaner assembly.
3. If necessary for clearance, remove the left hand wiper arm linkage.
4. Detach the wire harness connector from the blower motor.
5. Disconnect the motor cooling hose.
6. Remove the blower motor assembly retaining screws
7. Carefully pull the blower motor assembly out from the firewall.

Well first, if your talking about the radiator hoses when you say the bottom hose is warm and the top is cold, that would suggest to me a stuck thermostat. If not, then the heater core is located inside the truck under the dash. You can follow the heater hoses under the hood to the firewall and that will tell you where, under the dash the core is located. It is kind of a big job, as all the under dash covers will need to come out as well as the glove box. The heater core is inside the heater box, a black plastic box that will also need to be removed. It is important to note that when you are reinstalling the heater box after you change the core, it must be completely sealed, either with RTV or two sided insulating tape.
