WHY DOESNT MY 2003 CADILLAC SEVILLE HAVE ANY POWER AND DOESNT WANT TO SHIFT EASILY

1. Verify the exhaust system is not plugged. Check for less than 1.5 PSI backpressure at 2,000 RPM in park, or open the exhaust before the converter. 2. Check the Manifold Absolute Pressure Sensor (MAP) for 4.8-5.0 volts Key On Engine Off (KOEO) and about 1 volts at idle. 3. Check actual engine vacuum at idle at 2000 RPM. 4. Unplug the Mass Air Flow (MAF) sensor, reset fuel trim to 0%, and road test. ALSO CHECK FOR FAULT CODES IN THE OBD SYSTEM.

Cadillac CTS 2006 locking up and won't start due to anti theft system being triggered? Mechanics don't know what to do

You need a specialist rather than a 'mechanic'. An auto electrician with a professional grade scan tool computer can diagnose all the security system, the anti-theft immobilizer and all the modules and sensors in about 40 minutes. They also have access to the wiring diagrams and understand them. https://www.google.com/search?q=mobile+auto+electrician+near+me ..

Ground straps 2000 Cadillac Seville sts

Are you sure the engine is not grounded? Could be the starter relay. To make sure it is not a ground problem use a battery jumper cable and connect the engine to the negative battery post. Also make sure the battery did not lose its charge while working on the belt. Possible key left on.

My 2003 Cadillac CTS key stuck in the ignition and the gearshift is stuck

Is it stuck in the engine "off" position? 1.) Check your car battery. If it's very low or dead, it may be preventing the ignition from unlocking. If it's low or dead, charge it and try again. 2.) If the battery checks out okay, press firmly on the "S" button (sport mode) next to the gear shifter. Surprisingly, that somehow solves the issue sometimes. 3.) If that doesn't work, there may be a problem with the ECM. But try the two steps above first as needed, and if that doesn't work, feel free to post back.

How can I get into my 2002 Cadillac DeVille's glove box. It appears to be locked and I don't have the master key, just the valet key.

If you're having trouble accessing your 2002 Cadillac DeVille's glove box because it seems to be locked and you only have the valet key, here are a few steps you can try:
  1. Check for a Separate Valet Key Slot:
    • Some vehicles have a separate valet key slot inside the glove box. Insert the valet key into this slot, turn it, and see if it unlocks the glove box.
  2. Inspect for a Release Button:
    • Examine the perimeter of the glove box for a hidden release button. Some glove boxes have a button or latch that may not be immediately visible.
  3. Use the Main Ignition Key:
    • Even if you primarily use the valet key, try using the main ignition key to unlock the glove box. Sometimes, the valet key may not have the same features as the main key.
  4. Check the Owner's Manual:
    • Refer to the vehicle's owner's manual for specific instructions on unlocking the glove box. It may provide information on alternate methods or features specific to your Cadillac DeVille.
  5. Contact the Dealership:
    • If none of the above steps work, consider contacting your Cadillac dealership. They may be able to provide guidance on unlocking the glove box or assist with obtaining a replacement key.
  6. Professional Locksmith:
    • If all else fails, you may need to consult a professional locksmith. They have tools and expertise to help unlock car compartments, including glove boxes.
Remember to avoid using excessive force as it may damage the glove box. Additionally, make sure you have proof of ownership and identification when seeking assistance from the dealership or a locksmith. If your vehicle has an electronic locking mechanism, it's essential to rule out any electrical issues or malfunctions as well.

Where is the blinker relay at on a 03 cadillac seville sts

Turn Signal Lamps The TSIG/HAZ fuse in the rear fuse block supplies battery positive voltage to the flasher module. The module is part of the hazard switch assembly. The flasher module has ground at G201. The turn signal lamps may only be activated with the ignition switch in the ON or START position. The IGN-1 fuse in the rear fuse block supplies battery positive voltage to the turn signal switch. When the turn signal switch is placed in either the left or right position, current flows from the turn signal switch assembly to the flasher module. The flasher module then sends an on-off voltage signal to either the left or right turn signals and their instrument cluster (IPC) indicator. When the hazard switch is pressed, the switch contacts are close and the turn signal/hazard flasher module hazard input is grounded. In response to this input, the turn signal/hazard flasher module supplies battery positive voltage in an on and off flashing pattern to all the turn signal lamps. This also activates both turn signal indicators. When a THEFT is occurring, the DIM grounds the turn signal/hazard flasher module hazard input. The left turn signals have ground at G401 and at G402. The right turn signals have ground at G401.
