we've narrowed it down to something with the heater or ac not the carpets.
I guess that I misunderstood your earlier statement "...it seems to smell if the ac is not on...... you can smell it a little when the heat is on..... but its worse when nothing is on at all."
If it is related the HVAC system then it either grew there, or was physically introduced i.e. someone threw up into it. If it contains vomit you'll have to clean it out (not fun), but if mould has grown inside the HVAC housing, maybe due to lack of use or a blocked condensate drain, then it can be treated with a antifungal/disinfecting spray. These vary in effectiveness depending on the type of mould and the frequency with which the A/C continues to be used. Why not get some advice from a local independent A/C specialist, as some of the sprays are designed to be injected through a hole drilled directly into a specific part of the housing.

The original jack is normally stored under the rear of the passenger seat, with the accessories located on the inside of the passenger rocker panel. You could buy a small hydraulic bottle jack as a replacement.

#49 of 1888 heater noise?
Jan 30, 2006 (7:56 pm)
i have a 93 wrangler with auto transmission and a/c, about 110,000
miles. it's been sitting idle for quite a while, but the last few
times i've driven it, i've noticed an intermittent 'clunking/clacking'
noise coming from down by the passenger's side floor/dash. it only
happens while the heater is on. if i turn the heater off, the noise
stops, then comes back again when i turn the heater back on.
anyone know what this is?
thanks very much for your help.

Just to clarify, is this when the heater is on, or when the blower is on?

it's when the heater is on. it doesn't seem to make a difference whether the fan is on or off, or on low, or on high. i can turn the fan off but the noise is still there. but if i turn the heater to 'off', the noise goes away.
i really appreciate your time. thanks!

If the noise had varied at different blower levels it could have been caused by movement of the internal directional flaps, or even the fan blades making occasional contact.
With that ruled out it only leaves the circulation of the coolant, though there is a very outside chance that it could be something expanding and contracting with the heat. I would guess that it could be either a partially blocked heater core, or that one (or both) of the heater coolant hoses has partially collapsed internally. Instead of coolant flowing smoothly through, pressure builds behind the blockage then pulses through.
I'd treat it to a new pair of heater hoses, then using the new hoses, reverse flush the heater core with a garden hose.

it sounds exactly as you describe it - like pressure builds up and then there's the clunking sound as the coolant flows through again. thanks very much for your help.
i'll replace the hoses and flush the heater core. when i'm finished, i'll let you know if that fixed it. i'm pretty confident it will.
