heater and defroster blow cold air, and my a/c blows hot aireightysix 10-27-2003, 08:54 AM Ok this is kind of hard to explain. My heater and defroster will blow out cool air 90% of the time, but if I turn off the fan and just put the thermostat a hot the cab warms up from the astro ventaliation. The car in question is my '86 with a 305. I don't know why it is duing this. Plus when I put on the a/c it blows out hot air from outside. resq302 10-31-2003, 05:31 PM just a stupid question but have you recently had the vacuum hoses off of the heater box? if you did, maybe you hooked the vacuum hoses that control the direction doors up wrong causing warm air to go to the wrong areas? acauth1 11-01-2003, 06:11 AM just a stupid question but have you recently had the vacuum hoses off of the heater box? if you did, maybe you hooked the vacuum hoses that control the direction doors up wrong causing warm air to go to the wrong areas? Doesn't sound stupid to me, that's a good start. Someone or something, has probably fudged the vacuuming. | |
