On Amazon:*HEATER CORE: DRIVERS: https://amzn.to/2unOUh2*MECHANICS TOOL SET: https://amzn.to/2NctGIC*NOTE: When I made this vi 1. the first is to try to dislodge the clogging, and there is a DIY I wrote (and added others' info to) in the Information Base forum. do a search in that forum on "blues" authored by me. 2. the other is to remove the dash and replace the heater core. First reply to the thread was your really good DIY for clogged heater core. Now that it is getting colder I noticed that my heater wasn't working very well. The problem was being caused by a large air bubble somewhere in the heater circuit. I know when the bubble was created. Back in September the clip holding the rear CTS cracked and consequently the sensor blew out of the motor. At that time I had a difficult time getting all the air out. Step #3. Remove the passenger side panel. This is needed to expose a screw that holds the glove compartment, as well as give you access to the AC motor unit. There is a single screw that holds the panel. I believe it is a T20 screw. There is a "hook" on the inside of the panel, that slide in towards the engine. Hi, I'm looking for some assistance in trying to diagnose my 2010 B7 3C 125TDI CFGB engine Passat which is running cold. Initially I suspected the thermostat because even after an hour running along the freeway, the temperature would float around 50-60c (outside temperature between 5-15c). Next I need to work on fuel supply. VW draws direct from the tank with a tube that doesn't go all the way to the bottom so you don't burn the tank empty with the heater. Some people mount a separate tank. Having wasted so much time and limited brain power on the heater firing I have not researched the best way for me and will need to purchase .
