Posted to what seems to be (maybe) some of the problem that might be occurring. There is an exchange valve (best I know what to call it, it replaces the heater core thermostat that american cars have. It is located on my 1986 Nissan 300 ZX nontur/automatic, cal emmision, looking into the engine comp. the left hand side, there is a sieries of 3/4" hoses and a sensor like cylinder conected to the vacuum canister valve accuator with or without two wire connected too the sensor. The reason I wrote without is that this sensor (from what cars I have seen are missing the wires and there is a connector to it ussually empty) is a heat sensor, for when the car water temp is warm the valve is turned open, and when cool and if the AC is on the vavle should be in the closed position. Car auto idle up switch works fine, turn AC on RPM increases from 6 to 10 RPM, but hot air is all I get. Any suggestions before outside servicing, or can I replace freon myself?

86 300zx non turbo, the blower blows (Climate Control) but only half as hard as it was. It blows on low and high (half strength). It blows full blast when you push the manual defrost (override) button. HELP

#14 of 14 HELP Loose vacuum hose behind glove box by rkbatt

Aug 16, 2010 (7:38 pm)

I have a 1986 300zx and found an unattached 1/8" vacuum hose behind the glove box. The hose comes out of a T where the other 2 hoses go into a brass colored cylinder (servo?). Where should this hose be attached?
 
Thanks,
