[Mach 1]

Change it yourself. It nice to have heat, and the R2 process builds character. Just take your time and remove the dashboard and all the other crap in the way.

I just did mine on a Izusu Rodeo and it took me 2 days to get it apart, one week trying to get the right core (mine cost $170.00) and one day to get it back together, then I had to get the a/c recharged and replace a broke a/c line o ring, and replace the heater hoses.

all in all, a pain in the ***, but to save $400.00 in labor costs, well worth it.
