automatic heat

[2wdmuddin']

i dont know if this has been posted or not, but i need help. ive got a 94 3.0 supercab an when i gun it or when i hit abou 60-80 (which happens alot) the heater will just start blowin even if its completely off all heat and vent settings. what ive been doin is just slowin dow, which is hard and annoying as hell, but if anyone knows how to fix this problem please tell me. thanks

Does it stop as soon as you take your foot off of the gas? If so look at the vacuume check valve. Greg

sometimes it does but for the most part it just slows the heat flow when i let off
