Question about 2000 Volkswagen Jetta TDI

Jetta AC mixes hot and cold air

My 96 Jetta recently had the entire AC system replaced. Since then, though, I don't get ice-cold air anymore. I think I'm getting both hot and cold air, because when I move the temperature switch a half-inch away from total blue, I get hot air. Is there an inexpensive or simple fix? I hear there is a valve or flap that controls hot and cold. How hard and how expensive is it to replace? And does something control it that maybe is a better fix?

You won't get ice cold because it mixes to prevent evaporator ice up and cracked windshiels.

Only blows heat when accelerating


the ac core only blows cold air but You must be talking about the heater core.. In which case I would suggest that you bleed the air out of the coolant system as there is an air lock in the heater core.

Heater doesn't get hot on 96 chevy truck. Blows good, just cold. Replaced thermostat, flushed radiator. Any ideas?


Air Temperature Control Blend Door Failure No Heat or no AC (dependes on where door sticks)

In all modern cars there is a tiny DC electric motor driven gear drive that moves a plastic door that blends heated and cooled air from the AC and the heater core, this is called (interestedly enough) the air temperature control blend door actuator. The motor that moves this door fails because the door starts sticking from warping, most common complaint is no heat but it can be no AC as well. To replace these parts (blend door and blend door actuator) you must remove the entire dash from the car. Always have this problem confirmed by a dealer or qualified repair shop as it is a very expensive repair.

Other causes of no heat in the cabin are engine thermostats that are stuck open (engine runs cold) or air bubbles in the cooling system.

2003 Odyssey dual A/C Blows hot air front & back. High and low pressure compressor lines are hot. Is it feasible that the Air Mix Motor Assembly is the problem? If so, how do you check?


No the door would not be the problem. One AC line with the compressor running should be ice cold (large line) and the other line hot to the touch

2000 lincoln ls ac is blowing hot air on pass side


On the central console is the A/C module. Inside A/C module are driver's side & passenger's side air flaps for mixing hot & cold air and directed air flows towards driver's side & passenger's side according to driver commands. The passenger's side flap for mixing hot & cold air according to driver commands is bad. Flaps are actuated by electrical step by step motors. Could be damaged the flap actuator (motor), the flap mechanism (blocked in "HOT" air position), and / or electrical supply wires. You must access the passenger's side flap for mixing hot & cold air, and see what happens when you command cold air to the driver's side: flap mechanism, flap actuator, supply wires, ... Repair & replace bad pieces and test the A/C system.

A/C blows hot air even though the lines are ice cold


When your A/C is on the supplie of hot water to your heater core is cut off.For some reason this is not happening.It could be your heater control switch(red/blue...hot/cold)is not working,or your mixing valve that adjusts the amount of hot water that is suppied to the heater core is stuck open.

A/c in jetta blows hot air, its been charged, compressor comes on.


you need to have it diagnosed by a professional. These are complicated systems even to a trained tech. You may be over or under charged, have a clogged expansion valve, have a leak or many other issues. This model has a rcv refrigerant control valve inside the compressor which regulates the pressure of the compressor. If you notice the compressor never shuts off like conventional auto a/c's do the only time the clutch works is when you turn it on or off. Can be complicated.

03 jetta heater


Hi!
Looks like a classic air lock scenario! you need to perform a system bleed.
Park vehicle on level ground, when cold remove coolant filler cap. Start engine and leave to idle, turn heater to hot blower on full.
When at operating temp stand clear of coolant filler area, listen/watch hopefully gurgling and a boil over, top up when settled with very warm water/coolant, wait as it may do it a couple of times. Check for heat inside vehicle if hot and coolant settled replace cap but watch temp gauge for a while as another air lock may be in the system.
Please press the Blue button when sorted!

The ac in my 95 Jetta just works while the car is cool, then it stop


In addition to what emission wiz says, observe the speed of the fan when you turn on the a/c. some fans, when the are cold they run faster, then they get hot and slow down a lot. Also check that the small belt that drives the second propeller is ok. And for last, check that the front of the radiator is clear of any garbage, like a plastic bag that might have been cought in front of the condenser with the wind. If all this is working properly, there is nothing else that could be happening machanically to this a/c to stop it from cooling. look at the center of the pully of the compresor, make sure the entire thig is spining when clutch engages.
