Default Radiator fans dont Work..

Hey guys ,
So i finally got my car back on the road and then i noticed 4 bars in my Ap1. SO i immediately pulled over and let the car cool down. I never experienced this. As i tried finding the problem i noticed that the radiator fan doesn't turn on nor does the heat blow in the cabin.

Any ideas? Thanks

Bleed your cooling system if it was ever touched. There was air in mine. You'll know there's bubbles if the bottom radiator hose doesn't get warm.

From what i hear, yes this can affect the heat output. In my case it didn't but i guess it just depends on where you have air in the system.

When you bleed it on a cold engine:

1)lift the front end high on jackstands
2)take off the radiator cap
3)insert a funnel into the radiator neck
4)fill the funnel past the height of the filler neck about 2-3 inches. also fill you overflow a little past the max mark. squeeze/massage all radiator/coolant hoses until no more bubbles appear. add coolant to the funnel so that you don't suck the air back in.
5)crack the bleeder bolt on the drivers side of the head. fluid will come out. let it do this until you have a steady stream.
6)tighten the bleeder and add coolant to your funnel as necessary to maintain its level.
7)remove the cap on the hard coolant line next to the firewall and let it flow to a steady stream.
8)put the cap back on
9)take your funnel out and top off radiator
10)start engine and run with rad cap off until fan kicks in twice. put your heat on high as well.
11)top off and repeat as necessary.

Well man the bleeding didn't work so i just ordered a Fan Switch.
The coolant in the system doesnt leak as its at the same level. So im thinking its either the switch or the thermostat? What do you guy think?

What EMS are you using? Have you checked your fan settings in the EMS? They can be configured to come on at different temps.
