Thermostat stuck open, clogged heater core, heater flow valve not functioning, or low of coolant.
Check your fuses.
Fuel pump could be possibly getting weak. Happened to my blazer.
If a 1991 Chevrolet S10 Blazer warning brake light always stays on, it could just be a malfunction of the light. To reset it, disconnect the battery for 10 minutes.
Could be the vacuum actuator, or it could be an electronic fault, if you have an electronically controlled transfer case or an all wheel drive vehicle.
It is possible that the wiper pulse board is defective.
I wouldn't recommend it. You could cause internal damage. I have no idea why you would do this anyway.
Depends, It could be either the discharge or suction hose.
The stated towing capacity of the 2000 Chevrolet S 10 Blazer is 1500 pounds. There were options available that could raise the towing capacity to 3500 pounds.
Depending on the year of the Blazer some good accessories for the 2005 Blazer could be some new wipers, Exhaust, Spark plugs and ignition, brakes, transmission and drive train, fuel injector and some new shocks and suspension.
EVAP Emission control system leak (small). It could be as simple as a loose fuel cap.
If the fuel gauge isn't working on a 1999 Chevrolet Blazer it could possibly be because the float is stuck in the fuel tank. I had this problem when I got my 99 blazer, the float and sensor for the fuel gauge is on the fuel pump which is in the fuel tank to keep it temperature regulated. I had to replace my fuel pump, which ended up going bad on me, and after it was replaced the gauge works just fine.
checkALL of your fuses short could be a problem. i have a 95 blazer, bumps may of screwed up wiring like in mine
