Cadillac Escalade Troubleshooting

Do you need information on Cadillac Escalade troubleshooting? Or, need to know why there are leaks on the rear carpeting? The Cadillac Escalade is a car which was released over several years with variations based on the year and model. Based on the running and maintenance, there are bound to be issues and questions Cadillac users may have from time to time. At other times, problems can arise suddenly and troubleshooting information from verified automobile Experts can be helpful to deal with these issues.

Read below where Experts have answered a few questions for Cadillac Escalade car owners.

Why has water recently started to appear in the rear carpeting cargo area of the 2005 Cadillac Escalade?

If this Escalade is fitted with a rear sunroof, the drains can run right down the pillar close to the area of the leak. Apart from this, behind the trim/quarter panel is the HVAC case which houses the evaporator core. This also has a drain and if the drain tube gets clogged, water can back up and run onto the floor of the car. There is nothing much that can be done behind that trim. You may need to go below the car to locate the connections of the coolant and AC lines. A nipple type of object is seen protruding here which is either rubber or plastic which is the evaporator drain. Care should be taken not to poke anything in the drain, as it can damage the evaporator core leading to unnecessary expenses. The correct manner to deal with it is to blow compressed air in the drain tube. If this is not available, as a last option, a heavy duty plastic tie-wrap can be used to poke into and clear the drain.

What is the problem if the 2008 Cadillac Escalade repeatedly displays the P1175 code?

Case Details: The upstream 02 sensor was replaced on bank 2 as well as the intake manifold gasket.

The code P1175 commonly sets if the Bank 2 Sensor 1 has started to fail or if the injector is dirty. If the upstream HO2S sensor that was replaced is an aftermarket variety, it is better to try an OEM GM HO2S sensor. This is because aftermarket sensors have a poor track record and are low in quality. Additionally, it may be a good idea to have the injector cleaned professionally as this method is more effective than adding cleaner into the fuel. Having the injectors professionally cleaned consists of shutting the fuel pump down and running the engine using a can of injector cleaner until the can is empty. This helps flush out and clean the injectors thoroughly. This type of cleaning is usually carried out at any good automotive shop and need not be carried out specifically at a dealer.

Why does the functioning of the AC on the 2003 Cadillac Escalade reduce drastically when it is hot and humid or on slowing down?

Based on the description of the problem, this is a common phenomenon and occurs because of reduced airflow over the condenser while the car is moving slowly or when parked. The reason for this is most likely a failing fan clutch and/or debris in the condenser fins. To deal with this, the car should be taken for a high pressure car wash to blow out the radiator and condenser and clear them of debris. If this has never been done before on the car, there is a difference noticed in the AC operation at low speed. However, if the problem persists after the cleaning, the fan clutch needs to be replaced. Moreover, when it is an engine driven cooling fan as compared to electric fans, it is normal to lose some cooling capacity at low speed. Even with this, on a hot day, the air outlet temperature should not be over 60 degrees.

What can be done if the lift-gate on the 2011 Cadillac Escalade starts but closes within quarter of the way?

Prior to troubleshooting, one should be aware that this problem does not have a friendly, do-it-yourself diagnosis. To begin with, a scan tool diagnostics is available for this lift-gate and should be used to determine the information stored in the module about the lift-gate operation. Normally, a series of sensors need to work in a sequence. If not the computer detects the issue making the door go back in reverse. However, it is not possible to ascertain the issue without a scan tool that is capable of communicating with the lift-gate module. That would mean visiting the dealer or a well-equipped repair shop to have them scan as necessary.

Why does the cruise control and turn signals get deactivated when lights are activated on a 2006 Cadillac Escalade?  

The root cause to this problem is most likely poor grounding to the park lamp bulbs. Though there could be sufficient grounding to support turn signal bulbs alone, when park lamps get added, it is not sufficient to support the current load. The cruise control may not be functioning because it could be detecting stray voltage on the brake switch circuit. The problem could also be with wiring; however, it is more often because of issues in the lamp’s circuit boards. To troubleshoot this problem, start by disconnecting them one at a time to check if the problem ceases. If it does, the circuit board would need to be replaced.
