1995 GMC Sierra fan blower not working.
In the beginning you should check for voltage and ground.The 50amp fuse marked AC powers the blower motor and the motor is grounded.The high speed relay bypasses the resistor. So you should have power coming from the fuse and thru the high relay. Then the resistor for the other speeds gets power from the heat and ac control module which also controls the blend doors.You may need a shop manual or repair book to get the diagrams.
Clutch adjustment on 1995 gmc 1500
Sorry iam a europeon mechanic with no knowledge of this model but if i knew if it was hydraulic or a manual clutch then this would give me a better idea but if no play then its over adjusted causing the clutch to ride a bit hence the noise but how the adjuster works i have no idea here

Water leaking from bottom left of 350 engine
Sounds like a bad freeze plug but running the heat should not affect it. A cracked block is unlikely unless it has been frozen with not enough antifreeze. Does it only leak when running or does it also leak sitting still?
Will run but when you shut it off it will not restart
HelloThe engine
and automatic transmission in this vehicles drive train
are fully electronically controlled by a computer called the PCM
(Power Train Control Module). Whenever a problem like this occurs the
computer stores a record of the problem (there are of course some
exceptions to this, like the fuel pump, engine coolant temperature
sensor and MAF sensor for instance) in the form of a fault code in
its memory, to read these fault codes you must have the systems
memory scanned with a special tool. Once the fault code(s) are read
you then must perform the appropriate diagnostic testing to find and
resolve the problem(s) DO NOT REPLACE ANY PARTS UNTIL A
TRAINED TECHNICAIN HAS DIAGNOSED THE PROBLEM TO AVOID SPEDING YOUR
HARD EARNED MONEY ON PARTS THAT MAY NOT CORRECT THE PROBLEM
Got a 96 gmc nd i have a small hissing sound come
First thing I would look for is a vacuum line leak. Engine heat can make lines brittle or something like fuel or oil on lines not made for it will weaken those lines causing cracks, breaks, etc. Also a line could just not be connected (knocked loose during maintenance and missed). Sometimes these will affect performance but not always, and you didn;t mention anything other noticed issues. I'd check all hose connections of any kind as well.
How to wire fan switch for1997 gmc
i dont know what you mean, if you are tying to put a toggle switch in then run one wire from the fan to a ground on the truck and a wire from the toggle to the fan you will also need a hot wire from the battery to the toggle with a fuse inbetween, but the first thing you want to check is make sure the fuses and the relay are good and you have no broken wires if they are good then hook up a neg- and a pos+ wire to the fan if it comes on the change the temp sensor and the fan should work on its own when the truck gets hot
