It sounds like you're having some electrical issues with your 2004 Acura MDX. Here are a few steps you can try to troubleshoot the problem:

The first thing we need to do is check the fuse #9 and the accessory power relay here is a guide to help with the test please use it when the key is in the on position with the engine off. Also, I have included the fuse location in the images below.
