2002 GMC Yukon V8 All Wheel Drive Automatic 83000 miles
I have a 2002 GMC Yukon XL Denali that has the Autoride feature. Currently I am having a problem with the autoride not turning on. I did some searching on the internet for what would cause this and I get a diffrent answer everywere I check. I did see that some people have said there is a light that shows on the dash if the autoride needs service and I can say I do not have any lights like this lit. My current plan of attack is to first check if the pump has power. I know were the pump is located but what would the best way to check for power be? Does anyone know what wires are supposed to be hot? Another thing I just thought about is are those wires just hot when you first start the car when it would normaly pump up or are they hot all the time? If the pump does have power I heard I should check a ride control sensor (I think that is what it is called) but I do not know were this sensor is and what would I check on it? I do plan to replace the rear shocks since they do look to be origanal. Any tips and tricks would be very much apriaciated. I am not affraid to do any thing that is needed to fix this problem I just like to ask questions before I go ripping into these newer cars it is not like working on my Nova were I know I did it all from the ground up and I know what everything does.
I wish I could give more details I know that it is very helpful to you when trying to do this type of thing without seeing a car, but in this case all I can give on this problem is it is not working at all. If voltage readings would help or any other thing like this please let me know and I will get it.
