Okay i'll try to make this short and sweet,

I have a 94' and theres no heat and no cruise control ( possible linked?) . I had my dad help me change the heater core earlier this spring due to a massive coolant leak. The core was junk (or so i was told). So this was in april and it still didn't work, so i put off finding the exact problem till august. Now its october and I've done everything. Changed the thermostat, checked hoses, replaced the vaccum resivoir. Air blows out barely warm/cool air. I should probably mention that the A/C worked fine this summer. I think I may need to bled the air out of the hoses and I was told to look for a bleder screw? somewhere near the thermostat, any idea where I should look and if I should look at something else. Any help would be appreciated as I've posted on about a million other sites with no response. Thank you

Is the air that blows out still Hot? If so I would check the heater switch.It might not be converting from the normal air to defrost.I don't know on the year.But I do know that the cruise control is vacum operated and do know that some heater control switchs are too..I would check to see.

The air that blows out isn't hot at all

Can you here the the vent moving inside the dash?

No I can't, It just blows out cold air. It does blow out alot of it tho. Sorry my description isn't better.

What I would do is to check the hose pressure at the heater core.If you feel pressure it is not under the hood.It would be in the heater switch.

so where exactly is the heater switch? and also how to i work the bleeder screw to make sure there is no air in the lines?

how do i check for hose pressure?

The heater switch is the dial the you use to control from cold to hot.I have had to replace alot of the on my cars and friends too.Just start the car and turn the screw until you see fluid only.Also turn on the heater.Good luck!!
