What do these lines go to?

What do these lines go to?

Postby HootenWeb [OP] » January 7th 2019, 3:12am

Today while changing my shocks I found two lines that aren't connected. These are on the passenger side right by the top shock mount. Does anyone know what these are for? They are severely corroded and not connected to anything on the motor front end. I did not follow them to back.

Thanks,

Webster

They’re pretty bad, but they could be rear heat lines.

If they’re not connected, don’t worry about them.

Ok I didn't worry about the lines as suggested, but now it's 95 out and I have no AC. If I put some refrigerant in and these rear lines are not connected will I just loose all my refrigerant?

Is the front and rear AC separate?

Thanks,

No. Not really. The rear AC has a separate evaporator and blower motor (and blower motor resistor), but the single compressor up front does both.

The silvery line with the big connector, further away from the shock is for the rear AC. The other set, the really really rusty set, is for rear heat.

If neither set is connected to anything and it doesn't look like there's a matching set of hoses (for rear heat) or lines (for rear AC) that also isn't connected to anything, then they've been disconnected from the front systems and the front systems should be sealed.

Easy and inexpensive way to locate leaks in AC is to hook up air line from shop compressor to AC system and run it up to about 50 psi then listen for leaks. In your case check those mystery lines. But once everything is done and fixed you have to evacuate the s**t out of the system. Like about 4 hrs at max vacuum.
