Thanks everyone! I'll look again before biting the bullet and having it fixed. The whole system is nice and dry and clean (no oil spots or grime build-up). Even under the compressor (the bottom) is dry and clean. Yes, it has rear air (the whole reason for buying a Suburban in the first place). Very frustrating indeed!  I am with you on the rear air. Glad my Durango has it. But around here, rear seat warmers are the big deal. Drove to North Dakota without them in a rental car and never heard the end of that.  Craig
