Are you able to remove the knob safely? It sounds like the knob might be stripped but still hanging on. If you are able to get the knob off then you should be able to manually adjust the control using pliers or something to see if the knob itself is the problem or not.

    No, I just pulled it off and worked it by hand and it still doesn't change the temp.

    Then the problem is most likely behind the controls. You may have to get the control unit replaced.

    I have replaced the control unit in the dash and that did not resolve the issue.

SOURCE: location of oil filter on a 2008 hyundai elantra

It is located under the alternator. If you are looking down at the engine, it is to the far left. If you are under the car it is to the far right before the oil pan.

SOURCE: Can't find headlight adjustment screws

They nuts should be located either on the top of the headlamp assembly, behind the headlamp assembly, or near the frame rail by the radiator support.

Park your car on a level ground 30 feet from a wall and measure the height from the ground to the bulb and mark on a wall (do this for highs beams and low beams if the bulbs are separate, if highs and lows are the same bulb, only do it for the lows)

If the headlights read VOR, then aim the brightest part or cutoff part just below the mark on the wall. If it says VOL or nothing, aim them 2 inches below the mark on the wall.

How do i determine of my 2008 hyundai elantra is negative grounded or positive grounded?

If you have a multimeter, it should be easy. Black lead on frame and red lead on "hot". If you read -12 Volts, you have a positive ground. If you read + 12Volts, you have negative ground system.

Hyundai Elantra 2008 "ecs off" light is on, is this dangerous? Can we fix it ourselves?

It's not something you can fix yourself - it typically requires special tools and a very specific checklist of things to check in a special order.
Driving with the ECS is no more dangerous than driving in a car made before 2005. It simply means that it cannot automatically correct things like driving to fast into a corner or slipping on ice. If you stay out of the "pushing the limit" type driving and treat the car as if it didn't have any kind of electronic nanny controls, you should be fine.

I have a 2002 GMC Envoy XL that blows cold air from the rear heat vents. What could the cause be?

the heat accuator could be bad. It is a motorized part that adjusts your temprature by allowing cold or warm air flow when you adjust the temprature at the knob you are turning

Surging when hot, ok cold

Check your Idle Air control Valve and your EGR valve. Most of the time these will not set off codes but will give you problems like this and are easy enough for a none mechanic to fix it
