ihiryu Posted October 17, 2012 Share Posted October 17, 2012 Okay guys, I'm having a predicament. My A/C works, but my defroster, and heater no longer works. I've taken what I can apart and can't seem to find out what's wrong. My plan is to remove the heater core, and misc. heater parts. My plans are going to install a universal heater, such as http://www.summitracing.com/parts/SUM-991106/?rtype=1 Or the Flex-A-Lite Mojave unit. But has anyone done anything like this before? I know people usually do it backwards (removing A/C leaving heater). -Steve Quote Link to comment Share on other sites More sharing options...
Trevor Posted October 24, 2012 Share Posted October 24, 2012 If your Z is a 280Z, it's probably just a vacuum hose leak. Quote Link to comment Share on other sites More sharing options...
FricFrac Posted October 30, 2012 Share Posted October 30, 2012 Just had this problem with my 280ZX. Completely rebuilt the climate control system last year. Just started using the car and no heat. Long story short turns out the vac lines going to the vacuum pump were split - vacuum leak. Cut half an inch off both lines and it works great!
