My baby is a 94 3x locked fj80 but she is causing me some grief right now. I am really hoping someone can help. I have searched mud and all the rest of the internet but have found nobody with my problem. For some reason with the a/c on if it's cool outside the a/c for blow for a bit and then the heater will come on and I get 140 degrees out of the vents. I was thinking ambient air temp sensor (apparently 94 landcruiser doesn't have) or cabin air temp sensor (apparently only in units with climate control). Any ideas will help even if they are bad/stupid. I live in texas so 9 months out of the year you really don't want your car deciding what temperature you should be.
