Question about 1999 Dodge Intrepid
The heater on my 03 jetta 1.8T does not work there is only cold air coming out can you help me?ac works fine
Sure sounds like a blend air door problem. The rotary temperature knob moves a cable that moves the blend air door. There is a bushing in the housing that likes to break and will either leave the door closed no heat or open heat when a/c is on. TSB 8506-01 covers this problem.
A/C - Can't Adjust Temperature Output Control
85 06 01
July 11, 2006
HVAC, Temperature Output Control Cannot Be Adjusted
Customer states cannot adjust temperature and/or A/C is not cold.
The blend door control lever moves freely, but the blend door does not operate.
A bushing that fits on the lever may have a broken tab/clip, -arrows-, as shown.
This tab/clip may cause the bushing to fall out of the fresh air housing which can result in the door becoming inoperative and result in undesired air temperature.
No production change required.
In the past the entire fresh air housing was replaced because the bushing was not available as a separate part. The bushing is now available as a separate part.
The bushing can be accessed from under the center console.
^ Remove the panels near the foot wells at the passenger side of the console, -arrows-, as shown.
See Repair Manual, Body-Interior, Repair Group 68 - Interior Equipment for removal procedure.
^ This will expose the location of the control lever, -arrow-, as shown.
^ Re-bolt a new bushing onto the lever, -arrow-, as shown.
^ Re-insert the bushing with lever onto the blend door until it is firmly secured in the ho03 jetta heater - 1ec1246.jpg>Tip:
A mirror can be used to aid in identifying the orientation of the blend door when re-securing the bushing in the fresh air housing, -arrow-, as shown.
^ Reinstall panels.
Hope you are good at working in tight spots and with mirrors. I just did this job 2 weeks ago. It took 1 hour and was really a pain in the B==t working upside down with a mirror through a 1 inch hole. Hope this helps and Good Luck Happy New year and thanks for using FixYa.

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!
