Question about 2002 Volkswagen Jetta TDI

1 Answer

2002 Jetta A/C is not working.. It's blowing hot air (not warm, not air that's just 'not cold', but air so hot you can't keep your hand there long)... I had a problem with the radiator fans, but replaced them and they work fine, also just replaced a fuse (#5, which controls a/c, climate control, cruise control, that was missing), and it fixed my cruise control problem, but don't believe it fixed the A/C problem...

2002 Ford Taurus, Heater blows cold air?

My VW Jetta isnt warming up in cold weather the guage runs at 90 c on a normal day but on a cold day it is at about 60 c and when im in the city driving slower its at 50 c


Check t-stat. I might be stuck open and allowing the coolant to cycle continuously. This prevents the engine from warming up.

My heater in my dodge caravan does not blow hot air. When my engine finnaly heats up, it blows only warm air. Its a 2006


First of all make sure your anti-freeze is at specification level's as well as make sure With the engine cold start the vehicle remove the radiator cap and make sure you see the flow of anti-freeze while keeping your hands as well as your clothing away from moving parts feel both hoses going into your heater core if the one on top of hot one on the bottom is cold then you have a Clogged heater core in which case you will need to flush the system . a simple garden hose will do the trick simply remove Both hoses to the heater core with the hose at the bottom line apply the garden hose until liquid comes out at the top of the other hose will probably see a lot of gunk. Also ensure that the vacuum line to the round ball under the hood is connected and not dry rotted.this will cause a vacuum leak to not allow the switch to fully engage from cold to hot. I hope this helps you.

Nissan Altima no cool air blowing or hot air blowing


Hi!
It appears we have an Air lock scenario and you will need to perform a system Bleed.
Park the vehicle on level ground, when cold remove coolant filler cap, start engine and leave to idle, turn heater on full and blower to max. When engine reaches operating temperature watch and listen near coolant filler, keep clear as gurgling and hopefully a boil over should occur. Top up with very warm coolant and wait as it may do it again.
Check for heat inside vehicle if warm replace coolant cap but keep an eye on temperature gauge as the ~Air lock may have moved on from heater matrix/core so proceedure needs to be carried out again from COLD.
