So i tryed searching but i cant find anything... my heat just sucks really bad.. i put it on hot and it blows cold air then starts blowing hot air for like a minute and changes... and i dont have the ac on or the AUTO control... i have no clue what it can be ?

 

did you check all your heater hoses in your engine bay? they may have come loose.

 

no i havent first thing tomorrow morning i will check.. its crazy tho like 50 in my car

 

what can be wrong if the hoses are tight and it still does that ?

 

Check the vacuum hose that goes to the control valve.

 

check your coolant level also

 

where does that vacuum line go to? my heat didn't work so i looked at the control valve and boom, it's just hanging. i ziptied the servo open for now, but i can modulate how much it blows (that's what she said).

 

my control valve broke the other day so i just bypassed and my heater works fine and so does my ac....

 

i have a heater valve, 60 shipped, last one left.

 

checked everything the hoses the coolant level.. everything seems to be in place .. i have no clue what else it can be .
