I have the exact same problem. Started occasionally blowing cold air. Now I can't get the hot air to come through. Could it be a flapper door that open and closes depending on the tempurature setting?
From what you say,it sounds like the heater core has sprung a leak.It's inside the car and air gets blown across it to warm the car,Check your engine coolant isn't getting to low.You can bypass the core for a temporary fix by switching the heater hoses around.Bit cold in winter though.Hope this helps
the door for the air flow is controled by vacuum operated motor. there is a leak in that vacuum circuit. when accelerating, engine vacuum drops until the rpm levels off. when there is no vacuum to the motor, the default postion directs air flow to the defrost vents to make sure you're able to clear the windshield.
on the passenger side? if so the cabin air filter may be the problem,if so you'll need to remove the plastic grate there and you'll see the air filter under it,remove it and get a replacement at an auto store. or you may have a leak around the windsheild. to check the windsheild for leaks,start the car and turn the heater blower motor on high and roll all the windowes up,and make a solution of dish soap and water in a cup and usa a clean paint brush to go around the windsheild with the solution and you will bubbles if there is a leak.
there is a little motor in your dash with a flap that allows air to come forward or up by your windo it might be blown. For your air not being cold check your freon,a/c compressor clutch an your fuse also one moe thing,power to your a/c compressor.
It's normal for the A/C compressor to come on with the defroster to dehumidify the air so the windsheild won't fog up under humid conditions. You can still control the air temp. out the vents with the temp. select switch.
On most cars when you push a button or slide a lever to change your choice of location where you want the air to blow out louvers move inside the dash to redirect the air to your chosen location. When you switch from heat to AC other louvers move. These louvers are often powered by vacuum lines running from the engine. If one of these louvers is stuck or if you have a vacuum leak in one of the lines it may be causing your problem.
cold air is coming fromvent by windsheild
