Does an automatic have a clutch assembly? Would that and the compressor cause the noise as well as the air problems?

AC compressor has a clutch and bearing where the belt sit check that

Thanks so much!! Will the clutch and bearings going bad make the engine light come on as well?

need to check for DTC
it may be some thing else
that giving you check engine light

codes can help identifying the troubled area

I checked the coolant level which is fine. Not sure what to check next. Thanks!

ARE U HAVING ANY ISSUES WITH THE CAR RUNNING HOT?ALSO IS YOUR TEMP GAUGE READING A LOW TEMP OR AT NORMAL RANGE?

A low temp will often be a thermostat that is stuck in the fully open position, is the engine temp in the normal range or is it showing lower?

I changed the water pump and the heater started working, 13 months later the heater stoped blowing hot air why did this happen again what should I do please help

Make sure the engine is warming to proper operating temp. Next, with the engine running, warm, and the heater on, feel both heater core hoses. They should be hot. If not, try flushing the heater core. If they are both hot, check the blend air door for proper operation.

I turn on ac and extreme heat comes out the compressor does come on but the vent blow out heat not warm air but from the heater, not sure what controls the damper door

You have a problem with the blend air door. On your model year it is either actuated by electric or engine vacuum.

My air conditioner blows HOT air.

This past winter, I inadvertantly hit the A/C button instead of the heat and it started blowing cold.

I immediately hit the heat button...no problem.

Now, that the weather's been getting warmer, A/C just blows hot air.

A/C is fully charged with no leaks

Hoses (tubes) from the condenser get VERY cold but the cold air never seems to make it to the vents.

Anyone have a clue?

Thanks!!

Temperature blend door is stuck.

I had this above mentioned car and yesterday suddenly the fan that blows the hot air suddenly quit working. I mean it would not work at low speed, ( setting 1, 2 and 3 ) but it still works at the full. the problem is that it warms the car too much. How can i fix it that it works on all setting.

Very common for the resister to go bad
replace blower motor speed resister
