I'd like to preface this by saying that I'm pretty much a beginner in regards to working on vehicles. I'm good with standard servicing things, oil changes, wiper blades, etc. I managed to change the brake pads and rotors as well, but that's about the most I've done.

I have a 1994 Jeep Cherokee XJ. I was experiencing heat issues, so I was checking hoses near my blower motor, with the engine running. I noticed the sound of leaking air from one area, but didn't do much to mess with it. Today while I was removing the blower motor, I noticed that the hose was already breaking at the connector, and moving it just slightly caused it to snap. I've attached a photo for reference. The hose is located directly against the firewall, above the blower motor, and appears to run directly into the dash. I'm hoping I can just throw some sort of sealant around this, let it dry, and roll with it. What I'm not wanting to do is remove the entire dash, since this is my daily driver. I'm having a whole slew of other issues but in this specific thread I just need some advice regarding this hose and connector. I'd like to know what it's called, and it's function, so that I might determine the best course of action. Thanks in advance!

 

Sounds and looks like a vacuum line. Can replace it with rubber line probably.

 

I cant tell from your pic

what is the OD of the broken hose ?

in the FSM, (and on this forum) there exists a diagram of all vacuum hoses

slipping a length of rubber hose over a broken PVC line as a joiner is a known "fix"

 

Thanks for the input y'all, I'll snap a better picture when the sun comes up. I managed to break a water pump bolt earlier, so I'll be trying to pull that out tomorrow anyways

 

​​​​​​ Not sure what you mean by OD. I've tried to look at some diagrams but I guess I just don't understand enough to get what's going on, but they don't look like what's going on under my hood.

 

OD - outside diameter

 

Outside diameter

2 minutes late. 😝

 

Its probably the easiest route to take. You can cut off about an inch of the hose end that came out of the angled fitting to use as a test measurement piece and take it to whatever store is near you that sells rubber hose. Find a bigger hose that slips nice and snug over your test piece. Buy about a foot of it so you have extra, then measure out a piece of the new hose to slide over the broken end of the hose going into the firewall, and the other end of the new piece over the piece that goes into the fitting. It would end up looking like a chinese finger trap. A new piece of hose in between the originals, overlapping on both ends.

Hope that makes sense.

 

My wife ended up pulling the broken piece of hose out of the connector with a pair of tweezers and just popped the other length of hose right in, worked like a charm! Thanks for the assistance everyone. Now I gotta get my thermostat housing to stop leaking.
