    Hi, I removed the HEVAC display unit to replace two bulbs, the ones for the temperature control switches. The display was working before I took out the unit, but the display has stopped working when I put it back in and connected the plugs. I then removed the panel again, and took it apart...

    Greetings from Melbourne Australia. Well I wouldn't say it's been all fun but there is a sense of satisfaction in keeping what is a great car going. Over the last few months I've been putting my 2001 Vogue back together; I blew the heater core because I ignored the sudden temperature spike...

    When you press the key fob to unlock, the hevac fan on the passenger side (RHD) whirs into action. When you lock the car the same fan runs for a minute or two before sleeping.

    LHD 2.5DSE 1999 pre EGR/MAF Hi, I have an issue with the HEVAC I've been considering to check for a while. It's not that big of a deal but it could become one later on so better to deal with it now. As per the title. When driving on the street and making 90° turns I notice the air from the...

    Replaced all three servo motors on the HEVAC system. Also while I was in there, I readjusted all of the ductwork to make sure all of the connevtions were still tight and not leaking (as best as I could). I am happy to report that the HEVAC system now works extremely well. There is plenty of...

    hi all, Having read as much forum information as possible on the HEVAC LCD backlighting I launched into the job of renewing the bulbs.
