Air suspension fuse location 1999 cadillac deville
Cadillac Northstar owners to those whose vehicle is overheating .My 99 Deville was overheating turns out it was Catalytic Converter.Dont rely on PCM for code.If the Cat converter gets plugged up the heat will not get past converter it will back up into engine block causing overheating.My deville ran at between 190 & 201 degrees this morning.If you have a misfire the unburnt fuel goes into Converter and causes damage to converter (blockage).Alot of people overlook converter when overheating happens.

What are these codes for 92 cadillac deville
Hello williamcole7: My name is Roger and I will help you. The code 888 is a test code. This tests the L e d's of the dash cluster. All segments must light so you can read all numbers. The 70 code means the system is ready and able to function. The ff code is a current BCM code and is happening at the moment. The f 40 code is a BCM history code and means it was a stored problem or something that has happened. The f 40 code is for a air mix door problem. THe BCM would set this if you had an A/C problem. The E 48 code deals with the EGR system fault. I would check for a vacuum leak at the EGR solenoid. The hose is prone to deterioration do to heat from the engine. Code E52 deal with loss of voltage. A dead battery or a disconnected battery cable will always set this code. None of these codes will keep the car from running.The repair schematics are to extensive to send in a reply. Should you need further help ao assistance I will be glad to help. Please rate the answer. Thank You for using Fix Ya. Roger
