Hi I have a 99 4cyl ranger and my a/c air is only coming out of defrost...I found the problem and it was that the vacuumball line was broken and I changed it but when I went to check there is another line that is broken and its the silver colored line that it's next to the vacuum line and I dont know where it goes. Can anyone help me please

 

It goes to your heater control valve.....4 port valve connected to your heater core hoses. If that is leaking vacuum you will see your vents default to defrost in the MAX A/C position.

 

Thanks man... i just noticed I dont have heater control valves and hoses, is there any chance of tricking the system?? Without buying heater

 

You don't have a heater core?

 

Nope it got taken off , I live in puerto rico and it wasent necesary so it got taken off

 

Sorry my mistake I have the core but everything else got taken off

 

whats the weather like in puerto rico right now

 

Hot!! Lowest is 65 normally 73-100 F.

 

Well since you don't have a heater core or valve I would just cap off that line.

 

And what can I do about a/c coming out of defrost?? Any idea? Thanks by the way!

 

 

Thanks man!!
