Default Accessory Air Inflator not working (In Trunk, 2004 GXP)

Just for reference, in case anyone has this same problem.

On my 2004 GXP, I have this air compressor hookup in the trunk:

Name:  IMG_1704.jpg
Views: 274
Size:  190.0 KB

The button to the left actually says AIR on it, but its too sunny to tell!

anyways, the compressor was turning on as normal when the car was started (as indicated by the low rumbling noise under the trunk about 15 seconds after the engine is started, and lasting for about 3 seconds).

however, when I finally wanted to use the accessory inflator to add some air to my tire, I discovered that the compressor did not respond to the AIR button being pressed.

After taking it to Mr. Goodwrench, and spending the $100 on my x-tended warranty deductible, they had replaced the compressor unit and said that solved the problem. Of course it didnt and within 5 mins after I complained, the technician narrowed it down simply to the RIM (rear integration module).

after the 15 minute fix to replace it, the compressor and the accessory inflator now work properly! Don't be fooled into having to replace the ENTIRE compressor unit! As in my case, it was simply the RIM.

Good luck and happy driving!

That'* good to know. It sounds like they may not have spent as much time as required to make a proper diagnosis. In most cases, it is the compressor that fails and this may have led the tech astray. Great that it'* fixed. Warranty was certainly your friend. Either of those items can be a little costly

I don't know if this is normal but I notice mine running almost every time I stop the car completely. If I go through the drive through to get food I can hear it kick on while I am waiting at the window or when I order. I think it is running too often. I hardly ever heard it run on my 2002 SSEi but I hear this one all the time. Should I get it checked out?

I'm not positive, but if it IS the compressor thats running all the time, its going to do 2 things: drain your battery & gas, as well as potentially burn itself out.

The manual in my car says not to run the compressor for more than 10 minutes at a time, with I believe 20-30 min cooling periods in between! you should probably get it looked at, and if its under warranty, make them fix it!

otherwise, 10 miles after your warranty is up, it will prolly crap out lol.

Good luck and let us know what happens!

This sounds excessive. You may want to have it checked. There are several places you could have a small leak. Some (like the valve just inside the trunk lid where the accessory hose connects) are relatively easy to check. Others you will need to hoist the vehicle up to access with any ease. If you've ever had the black plastic panel out across the rear of your trunk, a connection may not have been re-seated there.

You should be able to check connections with a dab of soapy water while running the compressor.

Mine runs a lot more often in my GXP than in my old SSEi. At least twice as much.
The old car still has the original that works great, even though the rear shocks are toast.

Maybe its poor workmanship in installation of lines, connections, etc. that is causing leaks. I'm sure that'* what has caused all the water leaks in the newer models -- poor factory work - you can see it.
