I would check your coil pack is working correctly, then that your spark plug gaps are the right distance, then change your plug leads & check the points.....


I hope this helps....

WHEN SERVICE ELEC SYSTEM IS FLASHING. PLEASE CHECK FOLLOWING:- 1. Check for a voltage drop to the Power Train Control Module (PCM) and Electronic Brake Control Module (EBCM) when the problem is happening. 2. If the voltage is less than Battery Voltage (B+) when the problem happens check for a voltage drop through the ignition switch. Tech Tips: SERVICE ELECTRICAL SYS - 106 The IPC illuminates the SERVICE ELECTRICAL SYS -- 106 message in the DIC when one of the following conditions exist: • The Dash Integration Module (DIM) detects a malfunction that is related to the ignition switch. The IPC receives a class 2 message requesting illumination from the DIM. • There is a Powertrain related code present. The IPC receives a class 2 message requesting illumination from the PCM. Conditions for Setting the DTC P1574 A 2.5 mph or greater decrease in non-drive wheel speed in 0.4 second and extended travel brake switch or TCC brake switch indicating brakes applied and no transition noticed in the stop lamp contacts of the stop lamp switch. ALSO CHECK FOR FAULT CODES IN THE OBD. I’m happy to assist further over the phone at https://www.6ya.com/expert/uttamjeet_2f3adc18600f8ede

Have you checked the transmission fluid level by the book? (owner's manual)? That's what it sounds like to me. Color on the dipstick should be pink. If not it may be time for a good transmission shop inspection. There is an internal filter screen that if filled, will interfear with proper operation. Check the radiator overflow with the cap off. IF you have bubbles, you may have a cylinder head gasket problem. If not, gurgles may just be the expansion of fluid into the overflow tank. I googled DDM. B3832 you can too, sounds like nothing to do with the transmission or engine operation. You may want to go by an autoparts store and ask to read the ECU error codes if any. The transmission may have it's Own error code system. If so, transmission shop or dealer would need to review that information. If it's not the transmission, there may be a fuel delivery system problem.

Nope. Manual says it will overheat and could catch fire, but I imagine that's if it get's near the "ran out" level. Owner's Manual is here: http://www.google.com/url?sa=t&rct=j&q=&esrc=s&source=web&cd=1&ved=0CB4QFjAA&url=http%3A%2F%2Fwww.vadengmpp.com%2Fowners-manual%2Fcadillac%2F2003-Cadillac-Seville.pdf&ei=iAcLVeyiEoqngwTno4OIDQ&usg=AFQjCNFV9TalXoOCX8n1zyFUxwjDd7Mv4g&sig2=Xx28A8d_xthm95vazTKBpw&bvm=bv.88528373,d.eXY

Front blower has separate fan. Check fuses first.

check the switch and relay. Any heat producing component, seats , blower motors , rear window grids, have fuses and relays. If the relay is bad it does not matter if the switch or fuse is good ..Relays in GM cars are usually in a fuse box located in the engine compartment. There are two boxes one in the cabin and another in the engine compartment...check both. You must trace the circuit from it's source to the seats in order to find the problem. A schematic of the wiring would help. You may want to recheck your settings . You can turn the seats on and off for winter and summer auto start.

check owners manual or shop manual

no load it should not come on, only when you add to the cars weight

same relay? was it bad? chk fuse now!. lol.

From 2005 STS Owners manual:
Each TPM sensor has a unique identification code. Any
time you replace one or more of the TPM sensors,
the identification codes will need to be matched to the
new tire/wheel position. Each tire/wheel position is
matched, to a sensor, by increasing or decreasing the
tire’s air pressure. The sensors are matched, to the
tire/wheel positions, in the following order: left front (LF),
right front (RF), right rear (RR), and left rear (LR).
You will have one minute to match the first tire/wheel
position, and five minutes overall, to match all four
tire/wheel positions. If it takes longer than one minute,
to match the first tire and wheel, or more than five
minutes to match all four tire/wheel positions the
matching process stops and you will need to start over.
The TPM matching process is outlined below:
1. Set the parking brake.
2. Press the push-button ignition switch to OFF/ACC.
3. Using the Keyless Access transmitter, lock and
unlock the vehicle’s doors.
4. Press the lock and unlock buttons, at the same
time, on the Keyless Access transmitter. A single
horn chirp will sound, indicating that the TPM
system is ready, and the sensor matching process
can begin.
5. Start with the left (driver’s side) front tire.
6. Remove the valve cap from the valve stem.
Activate the TPM sensor by increasing or
decreasing the tire’s air pressure for five seconds,
or until a horn chirp sounds. The horn chirp,
which may take up to 30 seconds, confirms that the
sensor identification code has been matched to
this tire position. To decrease the tire’s air-pressure
use the pointy end of the valve cap, a pencil-style
air pressure gage or a key.
7. Proceed to the right (passenger’s side) front tire,
and repeat the procedure in Step 6.
8. Proceed to the right (passenger’s side) rear tire,
and repeat the procedure in Step 6.
9. Proceed to the left (driver’s side) rear tire, and
repeat the procedure in Step 6.
10. After hearing the confirming double horn chirp, for
the left rear tire, exit the matching process by
turning the ignition switch to OFF/ACC.
11. Set all four tires to the recommended air
pressure level as indicated on the tire and loading
information label.
12. Put the valve caps back on the valve stems.
