1. Check the battery: Make sure the battery is fully charged and that the connections are clean and tight. A weak or dead battery can prevent the engine from starting, even if it is turning over.

2. Check the serpentine belt installation: Make sure that the new serpentine belt is properly installed and that all the pulleys are aligned and spinning freely. If the belt is misaligned or one of the pulleys is seized, it could prevent the engine from starting.

3. Check the fuel system: Check that the fuel pump is working properly and that there is fuel getting to the engine. You can check this by listening for the fuel pump when you turn the key to the "on" position and by checking the fuel pressure at the fuel rail.

4. Check the ignition system: Check that the spark plugs are firing properly and that the ignition coils are functioning correctly. You can check this by using a spark plug tester or by checking for spark at each plug.

5. Check for error codes: Use an OBD-II scanner to check for any error codes that may be stored in the vehicle's computer. These codes can give you a clue as to what is causing the issue and can help you diagnose the problem.

The radio and speaker fuses in a 2006 Cadillac DTS are typically located in the fuse box under the hood. To find the exact location of the fuses for the radio and speakers, you can consult the owner's manual for your vehicle, which should have a diagram of the fuse box layout and a list of each fuse and its function. If you don't have access to the manual, you can try searching online for a diagram of the fuse box layout for your specific make and model. It's also a good idea to check the fuses visually to see if they're blown. A blown fuse will appear visibly damaged, with the metal filament inside the plastic fuse housing being melted or broken. If you're having trouble locating the fuses or determining if they're blown, you may want to have a mechanic or professional inspect the electrical system for you.

You can try searching for a service/repair manual for your 2017 Cadillac CTS 3.6 6 cylinder Luxury model on websites such as eBay, Amazon, or other online marketplaces that sell automotive literature. You can also check with Cadillac dealerships or auto parts stores as they may carry the manual you are looking for. Another option would be to search online for downloadable PDF versions of the manual, but it is important to make sure that the source of the manual is trustworthy and reliable.

1. Blown Fuse: A blown fuse can prevent power from reaching the heated seat system. Check the owner's manual for the location of the fuse for the heated seats and replace it if necessary.
2. Bad Relay: A bad relay may also prevent power from reaching the heated seat system. Check the relay for the heated seats and replace it if necessary.
3. Bad Heating Element: The heating element in the seat may have failed. If this is the case, you will need to have the seat cushion removed to replace the heating element.
4. Loose Connections: Check for loose connections in the wiring to the heated seat system. Make sure that all connections are tight and secure.
5. Control Switch Failure: The switch that turns on the heated seat may have failed. If the switch is not functioning properly, it will need to be replaced.
6. Bad Wiring: The wiring in the heated seat system may have become damaged or frayed over time. If this is the case, you will need to have the damaged wiring repaired or replaced.

If your car did not come equipped with headlamp washers, this spot will be empty in the fuse box.

cars sold new have 3 to 10 audio options. and are not the same wired. ever.! even engine options change fuse boxes. oops not told the service manual covers all that, why not buy it? or test all fuses in all boxes 5 boxes. cab/ and engine bay ? (look ma' no books me)??? or open glove box see users guide and is matched to your not told VIN and shows all fuses.! the users guide is free from Cadillac. get it? if lost? i,m teaching how to fish. here. next I delve into some brief specifics. no VIN told and not radio option package told this car has RPO data, , the RPO sticker shows (RPO is GMs name for "as built" options "THIS CAR" only. all codes for RADIO and now you know what is in any GM car made,.(GM will i fact decode your VIN and send you the RPO list. for free) the radio list is, day1, DTS

1. (US8) AM/FM Stereo, CD, MP3, RDS, EQ
2. (US9) AM/FM Stereo, 6-Disc CD, MP3, RDS, EQ
3. (UQ3) 8 Channel Amplifier (as fuse rear 20a )
4. (UQA) Bose 6 Channel Amplifier(rear fuse too 30a)
5. (U2K) Digital Radio

now the magic of networks here. "The main radio power is supplied by a 15A fuse located in the RBEC. The radio does not require a discrete ignition feed circuit for power moding. The power moding is accomplished using a structure of Virtual Networks (VN). The Power Mode Master (PMM) transmits the GMLAN power mode signals." so not scanning the car OBD2 port you miss out on key network and other errors (DTC) I will now decode that for you, it means scan the cars OBD2 port see why the radio is failing. UBEC means under hood RBEC means. rear compartment fuse block ok here is free cute video see fuses named audio. under set if havea powerful PA amp option there are more fuses. radio, and amp , audio. look or buy the SM. https://www.youtube.com/watch?v=hwOxLbkFG90 end.

Do you have any trouble codes? check for vacuum leaks!

have vehicle scanned the trouble code will assist in solving problem

You will need to refer to the Cadillac service manual for the exact sequence and specs. Generally, the torque specifications for the bolts range from 8-11 ft-lbs and should be tightened in the following order: (1) center bolts, (2) outer bolts, (3) inner bolts, (4) lower bolts.

My guess is Body Control Module comm failure, which would explain inoperative windows and door locks. Lighting is likely non operational also?

Check any/all fuses labeled BCM. You could also try disconnecting battery for few minutes and see if problem clears.

fit the TCM and use a scan tool to reset the unit

You can't. Fix the problem not find a way around it. Have a read https://www.fixya.com/cars/r29887709-gm_passlock_security_system ..
