My 95 Suburban has a max setting for Max cooling. The blower seems to run on all speeds. When I place the blower on high and place the temp control to MAX, I do not hear the blower motor go to a higher speed nor do I feel an air flow change. (My inlaws have a 99 Tahoe and it has the exact HVAC system as mine, when it is placed on high fan and max A/C I experiance a audible increase in fan speed along with increased air flow.)
My 95 has manual controls and has both front and rear A/C. 350 engine automatic with 4 wheel drive.
The A/C cools has it should, I just believe that I may have a resistor blown. I have checked the relays and the 50 amp fuse, all seem fine. Where can I find the resistor mounted? Any advice is greatly appreciated.
