the in-car temp control does not connect mechanically to the water valve.
suggestion?
-warm car up
-open hood and look at vacuum-controlled water valve (on firewall, pass side)
-get someone inside car to set the temp to cold, then shift it all the way to hot - you should see valve operate
-if no operation then is either not getting vacuum - or the VSV that switches vacuum to the unit is not being energised
also, see the TSRM on climate control troubleshooting: <www.cygnusx1.net/supra/library/TSRM/ac/AC_15.h tml>
