    Thread: 2002 Passat - Heater Does Not Blow Hot Air

    1. 12-31-2009 11:10 AM #1
      I have air blowing, it does not blow cold but doesn't blow hot either. Temp gauge is normal (at 190). Saw some posts that this could be several things so was wondering if anyone had some thoughts. Thanks!

      change your water pump, timing belt and tensioner, thermostat, and coolant temp sensor all at once to save you a headache but its your water pump thats bad

      remove rain tray and look at passenger heater core hose, you will see a small hole in the hose, you need to pull it and remove air from there.

      Heh. RE: hyperformancevw - unless you know you need a timing belt job, I wouldn't rush right in. Especially since it's more likely to be a clogged heater core or air in the system. If you haven't had cooling system work done lately, or noticed leaks or the level dropping, I'd vote heater core.

      Failed to mention that I replaced timing belt and water pump less than 1 year ago. Still think that could be the problem, or you think heater core. Isn't heater core big $$?

      Nah, the heater core is only about sixty bucks. Just pop out the dashboard, and replace it.

      Granted, it IS 8-10 hours labor to do so. Hopefully it won't come to that; look into purging air from the system, or unclogging the existing core, first.

      that would have been helpful to know. i have done several water pumps with the same problems he described. oh well let us know how it turns out.
