Ok so I had a Heater Core leak. Coolant all over my passanger carpet.So... I decided to bypass( reroute hoses under hood) the heater core untill i get a new one and get a chance to replace it but now my AC is not working. AC compressor turns on and air blows but not cold at all. My question is.... Does the heater core have to be working to have the AC working?

 

are you sure your heater core is leaking? does it smell like coolant? it could be that the evaporator water drain is plugged and filled with water to the point where water leaks and the air just isnt getting cooled because the water is covering most of the evaporator.

 

yeah I'm sure its coolant. smeells and looks like coolant. after I bypassed heater core,there was no more leak.... anyone else?

 

The heater doesn't stop AC function. You've got more than 1 problem.

The dashboard must be removed to to replace the heater core.

 

So there is no sensor that would not allow the AC to cool? The heater core is now bypassed so there is no water going thru the heater core at all. The thing is that the AC stopped working the moment I bypassed the heater core. Anyone else has any input?

 

I just checked it out again and the AC compressor does not activate when ac is turned on. The AC green light on dash turns on but the compressor doesnt turn on. Any Ideas?

 

Find a local shop that does AC work and take the car there.

 

i have a heater core if you are interested. pm me a price

 

I found the problem. The plug to the ac compressor came loose. It was just weird how it happened at the same time my heater core went out. Thats what threw off. Pluged it back in and it works great now. thanks to everyone for your help

 

I figured it was just a coincidence
