Air ride fuses keep blowing - 2005 Pontiac Bonneville

limited info generic answer a short is the most common cause for blowing fuses need a multi meter to check the components and circuit

You have a short to ground on the circuit that fuse protects . Viewing wiring diagrams for that circuit to see what all in powers up should be done , then isolate the circuit's till you find the problem circuit . Video's on youtube on how to find shorts . Which fuse box ? Under the hood in the engine compartment or inside the passenger compartment fuse panel ? # 11 in the underhood fuse panel is power supply for Air ride compressor relay . May be shorted relay .

Unplug compressor and other related parts and try the fuse then,,this will tell you which part is the problem.

Most air ride systems have a intial start up diagnostic program that will tell you there is a problem with your air ride system. Do you have any diagnostic errors kicking out? If you don't find the air ride on off switch and make sure it wasn't turned off by mistake. There is usually also a seperate fuse for the air ride systems (on my Lincolm VIII is is labeled RSS) which is close to the on off switch (my in on the drivers side rear quarter panel - trunk). That it if blows will totally skip the diagnostics on start up.

the fuse is it the right front relay/fuse box, 60 amps I think. Most likely the shocks leak, then the pump runs too much to keep them up, then the pump burns up and blows the fuse. There are companies that make a shock for the rear to delete the air ride, the air ride can cost a lot to get running again. shocks and compressor.

To begin with, check the "ride level" fuse and make sure that the ride level compressor does work, and you should be able to hear that the ride level compressor is working when the ride level system is leveling the vehicle.

The ride level system uses an air compressor and either an air type of shocks or a type of air billow to raise and lower the vehicle, there is an adjustment to set the ride height and it is located under the vehicle and there is a control lever or rod that should be connected between the rear axle and a switch that is mounted on the body of the vehicle, and there will be an adjustment slot in the control lever between the switch and the body, and that is how you would adjust the ride level height, but be sure that the vehicle can not drop any further down if someone is under the vehicle trying to adjust the ride height.

However, you might find that the control lever to the ride level has fallen off from the switch on the body or it has come loose from the rear axle, and it is just hanging there not operating the switch on the body that controls the the ride level compressor, or there might be a blown out air shock or billow, or you might find that an air line from the compressor is leaking and the ride level compressor will just run continuously until it blows out the fuse, and if that is the case you might also find out that the air compressor has burned out from running continuously.

I hope that this information will help you to solve your ride level problem.

i would say the light switch has a direct short, thats why the fuse blew in first place. they prob put biggeg fuse in to keep it from blowing. all good untill that shorted energy starts finding new places to ground or short out. always go back to original issue to find prob. good luck.

look for fuse under back seat that says ecas.my compressor also quit but i keep blowing the fuse when i change it .so i have other prob .good luck

We had the same problem but when we put in a new fuse it smoked. It turned out to be something with the master cylinder and required the changing of a 20 dollar part by the mechanic and problem solved

If fuse keeps blowing that means that there is a shortage on AC wiring or switch controlling the air conditioner.

Also an abnormal power draw from AC caused by an internal fault on AC can cause the fuse to blow.
Test wiring and switch with a voltmeter, the most common is that there is a short to ground between wiring and car body somewere.
