My 2003 gmc yukon put out a service ride control

Fuses have a little u shape piece of metal between the posts. If a short occurs, the center u shape piece will be melted.However if the comp works fuse is probably ok. Possible the ride sensor on the rear end disconnected or damaged .if shop did the replacement take it back to them.if you did it you are going to have to retrace your steps to see if something got missed

not that this is going to really help your overall problem but I can tell you that smelling antifreeze in the cabin and if the foormats are wet in the front then it is probably your heater core that has sprung a leak. Think of your heater core as a mini radiator but inside the vehicle and they are usually tucked up inside the dash somewhere and is usually quite expensive to have repaired because of all the labor involved. I just replaced mine in my 2001 Mercury Grand Marquis and it took me about 10 hours to change out. And i am a mechanic.As for your electrical problems I would personally contact the dealership and as them about recalls or technical bulletins concerning your 2003 GMC Yukon xl denali. Good Luck.

Ride control compressors burn up because of leaking air line or shocks. Replacing compressor won't last long if you have a leak. Most of these units are mounted under floor near rear axle.

ride control compressor is probably out

Seems like a common problem with these trucks. I thought I was the only one. I just posted this comment for someone who has a 2003.....I'm not an expert and not sure how widespread the warning message can be, but in my personal case: I have a 2001 Yukon Denali.....I have the same problem and have for many months. I took it in a few times and the GMC Dealership finally told me that It's the ride air bags. In my case they are leaking. Its not the same safety airbags in the front dash to prevent injury...but these models have air bags under the truck that automatically adjust to level when weight shift...you might hear the occasional sound coming from the back while driving or when more people are in your Denali. To me it sounds like a power tool. The Service tech told me it's not harful nor will it damage anything, but it costs about $2000 to fix, because they have to replace the whole thing. He said you may notice the sound coming on from the airbags more often because of this..because the system is working harder to adjust the weight due to the leak/loss in air. So occasionally for about a year...the light comes on....but it has done nothing else.

I hope this helps.

if your engine starts up and dies right away the you probably have a fuel pump problem and the service ride control mean that your air ride compressor has gone bad just turn your key to the on position and wait about 30 seconds you will here buzzing from the left rear wheel area if the compressor is working

may be a bad shock warning these are expensive.or could be a bad ride leveler or height sensor

leaking suspension air bags is the most common cause, but the system can be tested for trouble codes, I suggest u do so, only the dealer can do this, but guessing about what the problem is can get very expensive very fast.

The fuse is called RTD 30 amp under the hoodfuse box. That is for the Air Compressor.
