190e climate control
 

my climate control is screwing up the defrost vents dont shut off and the heat is always on and the air wont go to the flore. one time the pins for one of the connectors fell out and i had to guess were they went so if you have a wiring diagram that would help and if that is not the problem then please help me
thank you
p.s. it is a 190e 2.6 1987

Vacum hose?
 

I had the same problem on my 190e, years ago and what had happened was that one of the vacum lines broke or had a leak, it required more work than I could do, so I took it to the dealer, I think it cost me $197.00 for them to put in the $5.00 part. Sometimes I think I should have my head examined for liking 190s. ive had all kinds of little problems like that, which cost alot to fix. My toyota never had simple thinks like window regulators, vacum hoses , trunk switches, engine mounts, etc break so often.
