There are so many things that could cause this. the simplest and cheapest that may make a difference is fuel filter. Passed that, tune up.

I have a 2001 Chevrolet Silverado 2500 HD. A mechanic worked on it recently to fix electrical problems with the power window. Before the mechanic worked on the truck the Air Conditioner worked great. Now...

What engine does your 2500 HD have? Is it a 6.6 diesel, a 6.0 gas, or an 8.1 gas engine? If it's a gas engine, the A/C compressor belt may have snapped (common). The gas engines used a separate, smaller belt to drive the compressor, while the larger serpentine belt runs the rest of the accessories. Diesel engines only have one belt that runs all accessories, including the A/C compressor.

on most vehicles you have to remove the dash board to do this , but in rare occasions you can reach it from under the dash . P.S. it takes little tiny bulbs that are a pain from under the dash

I have a 2004 GMC Sierra 2500 HD truck with a 6.0 L engine. Every once in awhile when I turn the key to start the truck all the lights and power "blanks" out just like it does when you engage...

Verify all the battery cables are clean and tight, check for acid intrusion into the positive battery cable as well also check the battery cables at the starter and engine ground connections for being tight and having no corrosion.. Turn the nut and or bolts a 1/4 turn just to clean any possible corrosion under them.
