There should be a code reader plug in either underyour dash drivers side or under the hood close to the fire wall and you can buy a code retriever at any parts jobber or canadian tire.

98 caddy deville nothstar v8 how to replace heater coil have no heat and I'm loosing water somewhere


the heater core in a 1998 Cadillac is very tricky to replace.
start with getting a pressure test to determine where the exact location of the leak is, it may not be the heater core.
if you do decide to pull the dash apart to change the core make sure the battery is disconnected for at least an hour to allow the airbag system to discharge.

My 2000 cadillac deville will not shift into overdrive. throws no codes. what could be wrong? thanks for your time.


Is it not shifting into overdrive or is the (TCC) torque convertor clutch not coming on? If it is and O/D concern it could be a cracked shift solenoid, this will not set a code because the PCM only monitors electrical failures with solenoids. If it is a TCC concern the PCM should set a code related to a comparison between vehicle speed and engine RPM. Should. You need to have somebody access the on-board diagnostic program to diagnose the problem.

My cadillac deville has the following engine codes when hooed up: P0106, P0121, P0171, P0174, P0335, P0340, P0385, P0442, P0506, P0506, P0507, P0601.


click on the below links for code details.
P0106

P0121

P0171

P0174


P0335


P0340

P0385

P0442

P0506

P0507

P0601.

all of the above codes seem to have a common cause, they all list a bad ecm (computer) as being a cause, and the last code P0601 points specifically to a bad computer. sorry for the bad news, hope this helps.

Whath does "service engine soonmeans"


SERVICE ENGINE SOON and SERVICE ENGINE NOW are 2 amber warning lights pertaining to the vehicles computers.SERVICE SOON advises you of a problem, although not an emergency should be attended to promptly. Your technician can trace the problem by accessing fault codes through the climate control panel. SERVICE NOW indicates a more severe problem which will most likely precipitate a failure / breakdown. The CHANGE OIL LIGHT indicates by time and mileage is a separate light.
