2007 Cadillac DTS - Page 2 - Answered Questions & Fixed issues

are you driving over underground power cables when this happens?

Could be plug catalytic con.

I like the diagrams in Haynes and Chiltons auto manuals, available at auto parts stores.

alternator or battery faulty, or their connections

Bad battery, replace with new one.

very easy just a feww floorr bolts and wire harness after pulling up some of the carpet

check starter brushes and engine earths or volt drop from ignition to starter solenoid

by pass the starter motor see the diagrams attached. God bless you

Most of the warning lights get power from the same circuit, and are grounded by their sending units, including the engine computer. So if one warning light is out, chances are the problem is the bulb or the circuit board in the instrument cluster.

Most likely the brake interlock switch on the brake pedal is faulty or disconnected or the solenoid which holds the shifter is faulty or disconnected.

Could be a problem with the airbag itself or could just be a faulty crash sensor. Need to take it to a shop that has a scan tool that will read airbag or SRS codes. Most handheld scanners can't read them.

You will need the dealer to check this out, the reason is the alternator output voltage is computer controlled on this make of car and it takes special equip to diagnose the problems that cause this voltage drop, it could be the alternator for it could be a poor connection or a defective powertrain control module

plastic clips broke off you need to replace the unit or glue for cheap fix

To diagnose the problem you will need to disconnect the linkage at the transmission and see if you can manually move the transmission selector into park when it's stuck. This will tell you whether your problem is with the shift lever in the car or with the transmission itself. If you can't manually put the car in park from the transmission lever I would first disconnect the neutral safety switch to make sure it isn't somehow jambing the mechanism. The next step would be to drop the transmission pan and inspect the internal linkage.
The bushings gets shot where the shift linkage connects to the transmission. And this causes this problems.There is a direct linkage from shifter to the ******, that needs to be inspected.------ If the bushings are worn out, they needs to be replaced.------ -------- Getting this possibilities of shift linkage and bushings checked will help.Thanks.Helpmech.

To get to the bulb you would need to take the whole light assembly out. There are I think 5 screws holding the entire assembly and wiring and that should be it.

you should be okay as long as all the others are properly tourqed down, please rate

thay didnt replace the heater core??? this should have been done as thats where the water came from. when the carpet gets wet the seal on heater core goes bad causeing this. if you check it in about a week it will prob. be wet agine

Hello: Check the battery cables for corrosion (clean if corroded) and make sure cables are tight use a 5/16 box end wrench, NOT PLIERS.

Check the lock switch located in the glove box. It's their to avoid the Valet getting easy access to your trunk.
