replace the blower motor resistor located on the heater box were the blower motor is located the wiring to the blower may go to it. This is very easy to locate if you buy the part first.

SOURCE: Blowing ECM-B fuses
The ECM-B fuse is a 20 amp fuse, and you should NEVER put a larger fuse in to try to overcome any problem. The oil pressure switch is a secondary concern; there is an idiot light or oil pressure guage in the dash to alert you to oil pressure problems. Under heavy load, such as towing, your engine requires more fuel, and if your fuel pump is going/has gone bad, it cannot supply the demand.
The problem is almost certainly a fuel pump wire harness short, caused by a dying fuel pump. I have both had this problem myself, and repaired it on three other vehicles. On my vehicle, the wire harness had welded itself together when the fuel pump locked up, and the wire harness caught on fire.
The fuel pump is in the gas tank (of course my tank was full), and the tank has to be dropped to access it. The wire harness is modular, with plugs at both ends, and can be bought from the Chevrolet or GMC dealer.
If you put an incorrectly-rated fuse anywhere in your vehicle's electrical system, the WORST place to do it is where you have--the fuel pump circuit. Fuses blow for a reason, and the manufacturer's engineers properly size the fuses for the application at hand. Please don't do that again.
This can be a very dangerous problem and repair, and no, it is not cheap.
Do not attempt to operate this vehicle until you have had the problem properly corrected. Good luck.
