99 s10 heat module

Trying to replace the heater core in my 99 S10. Got the dash out, but cant figure out how to remove heating/ventilation module. Book says "remove mounting bolts and nuts". I dont even see any mounting bolts. any help?

I have the same problem! How did you make out?????

what book are you using?

Finally got it out. The manual says the mount nuts on located on the cab side but this is incorrect. All the nuts are on the engine side, except for three that on on the lower right side of the module looking from the inside. Its not too difficult once you find out where all the nuts are located.
