I had to change the core in a 1995 Sonoma PU.

You will need a long flexible extension. Works good if you have a drill motor. Under the dash there are a number of bolts that must be removed. Finally , on each side of the dash, remove the last two bolts. Now, remove the two nuts that hold the steering column up and drop the steering wheel. The dash now needs to be lifted slightly to unhook it off two saddles (one on each side) and slide it gently and just a little toward the seat. You can now reach under it to remove the last few screws off the cover and expose the heater core. You will have to uncouple the two tubes from it under the hood first. There are two clamps that hold the core in place. Remove these and the core will pull out. I found it was handier to have two pieces of wood about 14 inches long to hold the dash up off the floor so I could work under it but look over it. To replace the core, install it first into its cartridge and do up the two straps and then replace the cover for it. After that, its the reverse of taking it off, in no particular order.
