When I turn the heater on it does not feel as hot as it use to. And it blows cold air on the middle setting. What could that be?

 

thermostat

 

Or heater core or cable issue.

 

i call that year round a/c

 

LOL

Car gets hot as usual, so probably not thermostat. How can I check the cables? Also my coolant was low after the clutch install but I topped it off

 

Try burping your coolant

 

The coolant is still low and you need to fill it up.

 

Unlikely, but worst case it could bve a bad headgasket.

 

Check the cable on the heat control. They are known to snap. I am dealing with one now.

 

Incorrect mixture of water and anti freeze, add more water.

 

probally your coolant, make sure the mixture is right around 50/50, make sure you get all the air out. good luck

 

Mine does the same thing a lot. My cable is messed up so once in a while I have to manually reach under the dash and turn the lever for the heat door or w/e.

 

This. Mine only came unhooked from the control behind the dash, but apparently it had been like that for some time. I bought the car new, but I think it came off when I installed my touchscreen head unit. I thought the heating in the car sucked, but a local mechanic said it shouldn't be this way, looked under the dash and fixed it in like 5 minutes if that.

It is breathin' fire now.

Good luck

 

Is the heat cooler all the time or just when idling?
