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 'undeliverable', please

Dear MW: Thanx for responding MW. I dont have to floor it,
example , jumping on the frwy, or passing a slower car. it might be a
vacum 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.
