I have some old brittle multi-colored hoses that have snapped, and I don't know what they are to replace them but I think they are part of the a/c system. I've searched through my parts catalogs, and the local autoparts guys know jack about fords, let alone an older ford. My CEL is on, however it doesn't seem to affect my driveability. I don't have a reader to check the codes, and the parts guys here can't (or won't) give me the time of day "because" it's obd1.

All help greatly appreciated.

The first pic is from the grill, the broken lines are to the right of the intake mani, near the firewall.

The second pic is from the driver's side, with the mystery assembly nobody knows anything about.

The third pic is another broken line from my egr valve that may or may not be part of the same system.

Go back to the parts store and ask or get a Haynes Repair Manual. It's a DIY step by step manual that will have all of the diagrams for everything you will need. As for the codes, you can DIY with a bit of wire Click HERE

You should be able to get a Haynes Manual from most stores that have an automotive department. It's a good $20 investment. As for a Code Reader, which will give you numbers, instead of blinks, there is one online for under $30, but I don't have the link to it right now.

I see no pictures, but by your description, I'd say they are probably vacuum lines.

Yeah, I forgot to watch my Sesame Street this morning, sorry.

Vacuum Lines. Use small pieces of conventional vacuum line to repair what you have. Just slip it over the broken line and make sure it fits tight.

According to the schematic, That mystery solenoid is the Thermactor Air Diverter Solenoid (TAD).

But then the manual shows a very clear drawing of it, and calls it a EVR Valve.

They go to the egr vacum soleniod I think thats the right term for it. I replaced mine.

I found a thread from a bronco forum that looks relevant. TAD and TAB solenoid function testing.

Gonna do a little more homework, and I'll let y'all know what I find.

Okay, the green and black vacuum lines feed the EVR (egr vacuum regulator for anybody like me who hadn't heard of it before it crapped out). The black line connects the EVR to front-most solenoid (still not sure which one it is), and the green runs from the EGR to the EVR. I have no clue which line connects to which nipple, but I'm gonna see if this kills my CEL
