The left wheel isn't working as well. . Take off wheel and caliper. Free up the sliders that the caliper bolts screw into. You may have to remove bracket and heat

the front axle actuator is stuck engaged. the actuator is located on the right side of the front axle. the part is easily replaceable.

No, but if you're having a problem with erratic wiper operation, check the contacts in the control board that bolts onto the wiper motor.The contacts become worn and create wiper motor problems. The circuit board can be purchased separately at most parts stores and is easy to install.

Make sure the starter gear is not to close to the flexplate you may have to shim it.

I would start fuel cap. Check the o Ring. If in question replace it and reset your check engine light. Then I would inspect the evap system from the fill, to the tank, and up to the engine. Could be the selenoid or the carbon filters if they are on this vehicle.

install pressure gauge and watch when key is turned off to see if pressure drops to zero if so bad drain back valve in fuel pump replace it or deal with it or could be cheap aftermarket pump and has hard time building unnecessary pressure to open poppet valves between before fuel injectors

dont forget theres a set of fuses under the hood on the gmc as well as the ones in the cab! The ones under the hood tend to blow when hooking up a trailer and if you have turn signal issues or radio issues it's probley the fuse under the hood thats blown! Good luck

Check your batteries voltage you need at least 12 volts.If you don't have 12 volts then put the battery on a 2-4 amp charge for 6-8 hours.Then if the battery does'nt have 12 volts get a new battery.If your battery has 12 volts afterwards and still cuts off then your alternator is faulty.With the engine running your alternators power wire should show 13-15 volts coming out.

Could be a slight vacuum leak or maybe just a dirty throttle body.

Could be your thermostat. Why did you have to fill it up. If there is a leak fix the leak. I would always recommend filling coolant with a cold engine for safety.

Sounds like it could be the booster. Make sure the vacuum line is attached to the booster and the engine securely. If it is, could be the booster.

you need to have car evaporative emission control system check.sound like you have lots of gas fumes and vapors.built up causing pressure in gas tank.making fuel hard to pump in gas tank.

check out the hub and the cv joints if it does noise while moving if noise while just turning =check power steering pump /fluid and the belt for correct tension
