Cadillac Repair: 1993 Cadillac Eldorado Fault codes I033, I034, I037, cadillac eldorado, test procedures

Question
I've got a problem several other people have asked about. I get the check engine light coming on, and -- showing on my readouts, with the defrost blowing warm air. I pulled the current codes and got I033, I034 & I037.

I replaced the PCM, with no affect.
Any help would be appreciated!

You will need, If necessary, Electrical schematics, Test procedures and picture locations of the components within the system that is causing you problems of which can't be done on this website which only allows one picture.  I do not have a website so you will have to e-mail: onlineautohelp@msn.com in order to obtain the information.
