Re: Comprehensive guide to converting from A/C to heat only?
Because the firewalls are different on AC vs NonAC cars and the heater box inside is different, save yourself some grief and use one of the aftermarket ac delete boxes, like this one:http://www.ss396.com/chevelle/AXB-9B.html
The rest of the stuff on your list won't have to be done.
Alan, that's the box I have in my car now. I'm actually in the process of gutting the interior (due to rusty floors) this week so I want to make sure that there's nothing else I need to change.
I guess I should have realized it, but the A/C control unit is considerably different to the heater-only unit.
Do I need to reconnect the vacuum pods down at the bottom of the kick panels? What about the one in the windshield cowl?
