Hi; I believe the cigar lighter is on that fuse and that was a problem on these vehicles.
SOURCE: ecm fuse keeps blowing
just fixed this problem, change your fuel pump module, fuel sending unit shorts out on fuel level swing arm blue wire... unfortinately you must replace it as unit because of the design, fuel pump and tank guage fuel level sending unit are a one peice item, fuel tank has to come out to change unit, about a $ 700.00 repair too... fuel pump module runs about 350 to 700 $ depending on aftermarket or factory, try to find one with a lifetime warranty even if it is $ 50.00 more worth it..labor is about $ 250 to $ 400 depending on shop labor rate... definate problem though I ahve no doubt, common problem on GM... please rate my help, thanks...

the earlier GM trucks had a problem with the a/c systems
Compressors are junk, but this will usually break the a/c belt, and make a horrible noise right before that.
the pressure you have listed is not much help, there is a high and low side pressure. If they are both the same, then the compressor is not on or is not pumping (broke). The early yukons/suburbans/tahoes also had a problem with the a/c cycling switch. If yours has a brown band, replace it.
At Idle (depending on outside temp) Low pressure should be about 40 psi at idle and high side about 220....again this can change greatly by outside temp.
Another thing you may want to look at is of course a leak in the system, make sure its fully charged, and check the fan clutch.
