THAT CODE IS FOR THE LOCK UP TORQUE CONVERTER CLUTCH ,NOT WORKING /MALFUNCTION DUE TO SOLENOID PROBLEM OR CONVERTOR INTERNAL TRANSMISSION PROBLEMS. SEALS, INPUT SHAFT,O'RINGS, VALVEBODY ISSUES .MOST LIKELY NOT A SIMPLE FIX.

THIS IS SOMETHING THAT AN EXPERIENCED TECH NEEDS TO CHECK OUT .

HOPE THIS HELPS

I have a 1993 cadillac deville and the heat is not working properly it blows out air but cool air instead of hot


The most common cause of this is that the air temperature control door (called a blend door) is stuck or the tiny electric drive motor that moves it is defective. You will need a good shop that fixes AC/Heater issues to diagnose this, I am just guessing based on past experiences with GM (Olds and Cady) cars. A picture of the little drive motor is below, the door it moves connects to the hole that has white.

My 1993 cadi deville keeps flooding. gas fills-up in carbator when I turn key on. What's this?


first, the 1993 cadillac deville should have a throttle body not a carburetor. And, I think it has ported fuel injection to each cylinder with a fuel injector for each cylinder if it's like my 1990 Cadillac Deville.

The code on my 1993 cadilliac sedan deville comes up with E-39 what does that mean


E39 means that your overdrive in the transmission is not working which will greatly effect your fuel mileage.

The most common fault is the TORQUE CONVERTER SOLENOID that is faulty.

I hope this helps you

My code is e52 and f11 what is the problem


E52=memory(history)has been resetmeaning the power to the computer
was disconnected and the driving/engine systems performance history has
been lost.

If they are ONLY displaying as F codes this means that they are HISTORY codes and if they display as FF codes then they are CURRENT codes and what we need to diagnose is ONLY the CURRENT codes.

F11 = AC high side temp circuit problem.

hope this helps good luck

Error Codes


These may have been set by the battery change and are what GM calls phamtom codes, clear the codes with the following.
Try this and see if the codes go away.

1. Re-enter diagnostics via the climate control panel and after all the codes appear you will see .7.0

2. Simultaneously push and hold the OFF and HI (^) buttons on the climate control panel until you see E.0.0 and release both buttons.

3. Turn ignition key OFF, Wait 15 seconds and re-enter diagnostics and see if the codes reappear. If they do NOT reappear, You are good to go.
After you have done this try starting the engine and see what codes re-appear, also run and OBD 2 test of the system at the diagnostic connector, this will give P codes that we are better able to find definitions for, the E codes are unique to just a few GM cars.
