Hi Ruben, thanks for visiting. Could you give me a little more info please. On rapid
accel., does it start to blow cold after you let off gas and stay steady?
Do you hear any noises just before it starts to blow warm? Can you tell if the
compressor cyclys off when you hit the gas? This and any more info may be helpfull
for me to give some help, thanks. (Your e-mail address was returned as

Heater and A/C problem on my Chevy Tahoe
Visitor,
Dear MW: Thanks for responding MW. I dont have to floor it,
example , jumping on the freeway, or passing a slower car. it might be a
vacuum problem cause , i zipped tied the heater core valve closed and
the problem went away but now no heater of course. My email is down for
the moment
MW:
Sounds like you are almost there. Check that the hose has vac. and it
switches when you turn the system from heat to cool. Check that the
vacuum hose is routed correctly per the underhood vacuum diagram and
let me know what you find.
