The radio and windows share nothing in common electrically.
Each is powered on their own circuit.

The ONLY problem you could be experiencing is the Accessory Time Delay Module (AKA RAP Module)

This is a module that senses the vehicle is off - and allows some of your accessories like the radio, and lights to continue working for 15 minutes after the ignition is turned off, or you open the driver's door.

This module sounds like it has a bad ground, or bad internal switching relay.

This is a dealer-only part, and while you are there at the parts counter (should you decide to replace the module yourself) they can give you the exact location - as different trim levels have it located in different locations.

Thanks for using FixYa!! :)

Cadillac cts 2003 3.2l engine the timing belt jumped time i replaced the set it back on the timing marks an it didn't start i a code po 341 so replaced the camshaft position sensor didn't start


The same thing happened to my 03 CTS. The camshaft position sensor code is often thrown for a variety of reasons. In my case somehow the ECM went when the timing belt jumped (after the serpentine belt broke). It was a bear to diagnose but after installing a rebuilt ECM it runs great. (Don't make the mistake I made: the cylinder head gaskets will fit nicely on either side but if not placed on the correct sides you'll block the single oil port which provides engine oil to the head)

there would be 2-3 large vacuum hoses going to it which will help in finding it.

Have a 2003 cadillac cts my car will crank but not turn on some times it will start but i will be driving and get to a red light and it will completly shut down on me it does not always do this at times it...


how many miles are on your car ? will it start up after it shuts down or do you have to wait 20 or 30 min. had a problem like this with my own car it had 1600,000 miles on it. do you have any warning light on dash when this happen, if not, it's most likley it is the crank position sensor. it's about $60.00 at the dealership, not fun to put in. also could be a fuel pump problem, have a pressure test done on pump first before you buy a pump it is about $400.00 + $600.00 to put in. I haven't seen to many pump problems without a lot of other issue while driving. If warning light are on, have the computer scanned first.

good luck bro,
i have done many CTS's like this and all turned out be the sensor.

I have a 2003 Cadillac cts it drives fine but if im at a red light I shuts down but not all the time


Sounds like a possible fuel filter. Bigger question - when was last tune up? With the different grades of fuel these days and with temps fluctuating a fuel filter would be my first thing to change.

WHERE IS THE CRANK SHAFT SENSOR LOCATED ON A 2003 cts cadilac


The sensor itself is located under the car right behind the oil filter. It is connected on top of the motor right by the fire wall. You will need an E8 torx socket to get it out but it's a very easy replacement.

2003 cadillac cts drive shaft is making knocking noise


My 2003 CTS had the same noise problem while on vacation one day. When I returned from the vacation and dropped it off at the Caddy dealership it was revealed that several of the "U" joint nuts had worked themselves loose. A quick fix was to tighten up the "U" Joint bolts and the problem was solved!
