9/28/2013 HouseCallAutoCheck the air intake boot that is located between the intake manifold and the throttle body for a vacuum leak at the bottom. This is the narrow boot not the big one one. Spray some water there or some carb cleaner and if the idle speed changes or becomes more erratic then you know you have a leak there. As the engine warms up the rubber boot becomes bigger from warmth expansion and the leak is sealed up.

9/11/2013 HouseCallAutoWhen the starter does not function and you suspect a bad starter, get access to the starter and see if the small wire going to the solenoid gets battery voltage when the key is turned to the crank position. There are only 2 wires at the starter, a small one and a fat one.

9/2/2013 HouseCallAutoYou must plug in a code reader and see what fault codes are stored, especially since this may be caused by a security system fault. This would leave a code stored. This is how this is diagnosed, you start by reading codes. You can read codes on Cadillac without a diagnostic tool by using the push buttons on the information center.
DTC display; 1998-2004 Seville, 2000-2005 Deville and other models with 3 buttons on the RH side of DIC
Use the 3 switches located to the right (LH drive cars) of the Driver Information Center (DIC) to activate and respond to the OBD prompts on the DIC.
ON/OFF = YES
INFO RESET = NO
INFO DOWN or INFO UP = manual toggle
Ignition ON, acknowledge any warning messages; press ON/OFF and INFO UP together for 2 to 3 seconds. Everything in front of you lights up for 4 or 5 seconds, then you will see:
Display shows "ALL?"
Answering YES will display "ALL CODES?"
Answering YES will run automatic test sequence and display codes, if any. Systems and codes will scroll faster than I am able to read them and write them; not to worry.
"ALL CLEAR CODES?" will display at the end of the automatic test. If you are satisfied you have the information you need, answer YES to clear/erase all error codes.
Answering "ALL?" with INFO DOWN will toggle systems test manually in order.
Answering "ALL?" with INFO UP will toggle system test manually in reverse order.
Press INFO RESET to reset DIC to "ALL?" to start again.
Ignition OFF to exit.

9/1/2013 John's Auto RepairAre you certain that you removed the right relay for the fan? Because with the relay disconnected
there is no way that the fan should run. The signal for fan comes from the computer, to the relay,
and the relay engages the fan.
