Cadillac Repair: check engine light and serivice engine light, cadillac sedan deville, oxygen sensor

Question
I have a 1994 Cadillac Sedan Deville 4.9 Liter engine.The car runs very good but the check engine light and the service engine soon light come on, but not all the time. I've had it serviced but the mechanic could't find any thing wrong.Now that summer is here I've noticed when the lights come on that the air conditioner doesn't blow cool air and when the lights go off the air blows cool.I started the engine and pressed the off button and the tepture button and wrote these series of number down.
8.8.8, ..E, E13, E47, E85, ..F, F32, .7.0
Can you please help?  

Answer
These codes are NOT for a 1994 vehicle. Check the CORRECT YEAR of your vehicle !!!!!!!!!!!!!!!!!!!!!!!!



E13 = oxygen sensor fault.   

E47 = BCM (computer) to PCM (computer) communication problem.

E85 = Throttle angle to high.

FF32 = PCM (computer) to BCM (computer) communication problem.
