Question about 2001 Volkswagen Jetta TDI
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 I have the same problem. would it be the same for a 2001 jeta gl?
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.
