Air con........again

[Towpack]

To quote from the Amazon section of the 1997 Toyota sales brochure:

"The system also has a dehumidifier to prevent windows fogging and improve visibility, plus a special filter to help remove fumes, airborne pollutants, pollen and stale air".

So where and what is this "special filter"?

When my aircon goes unused for long periods, in Winter for instance, it sometimes gives off a strong 'sweaty sock' type smell when first switched on but I think this is from bacterial buildup somewhere in the system brought on by condensation left when the system was last used. One of those in car aerosol aircon fumigation/deodourising canisters usually clears it up.

Crikey! Mine has the damp odour if stood for some time but there is defo no filter. I've even had the evaporator out to try and fond the pipe leak I had. On the 100 the filter is behind the glove box. Most filters slot in like a cd drawer opening. You just slide the filter out and slide a new one in. Your access must be behind the glove box or possibly on the underside of the a/c box where your feet go. Perhaps you could see it with a mirror. Have you tried toyodiy with your chassis number?

This shows an interesting article converting a none pollen filter 100 to a pollen filter one. It shows the typical location of a filter.

Did a search on ToyoDIY and Amayama (looks like these source from the same database anyway) and came up with nothing. If you do a general inet search for LC pollen filters, 100 series filters come up but nothing for the 80. When the rain stops I'm going to have a root around behind the glovebox area and see what's there.

If you have a filter it's well past it's sell by date . If you have one there will most likely be a vertical slot in the RHS of the evaporator container. Or a horizontal slot underneath. The filters are normally on the outlet side of the evaporator container and before the heater matrix so I can't see where else it could go. I notice you can buy filters in sheets and cut them to size yourself if you can't find a Toyota part number. Very interested to see what you find.

Here's the view behind the glove box.....



I'm assuming the large plastic housing contains the evaporator. No sign of any sort of slot or orifice anywhere on the unit for a removable filter similar to the 100 series. The whole setup looks very different to the photos in the above link. So either there isn't a filter after all, it's a 'sealed for life' filter which would be a daft idea IMO or the filter is mounted somewhere else. Maybe the unit can be removed and the 2 halves split to reveal a filter but this looks a mammoth job. I guess the view behind your 80's glovebox will be identical to this Frank?


Edit.... Just looked at the exploded diagrams of the cooling unit/evapotator in the FSM and there is no filter shown. The system shown is from the earlier 1HD-T engined vehicles so, unless the last production run of the Amazon badged 80 series had a modified system, it looks like the pollen filter is a myth.

Yes that is identical to mine. My evaporator takes up the whole of that box and you can't get it apart nor drop the bottom part off without taking the pipes off. There's no room inside for a filter on mine. The box outlet is to the RHS so you might find a slot further over to the right in the area out of shot. Or there may be a slot underneath.

Yes the 100 series is completely different but the link illustrates the general idea. My 2004 100 has the plain cover so would have to be converted to take filters. I think one is a pollen filter and the other a charcoal traffic fume filter.

I did a bit of googling and found "Lucky" in the other place talking about filters on the very late 80's.

My June 95 80 does not have a pollen filter.

I did not thing there was Frank.

There are 3 thermistors Dave. The two you mention for external and internal temperature and the "sunlight" thermistor located on top of the dash panel.

That is not on my 94 80 Frank....least I do not recall seeing it. Perhaps that is why my 'Climate' is lazy in responding to moving the slider from hot to cold? Takes a good minute or so to shut off the heater valve and bring in the compressor.

Up the mountains today moving trees off a property a friend has purchased, so good to make use of the 80's 'grunt', he cut them down in readiness and hooked them up, and I dragged them down to the waiting truck, he could not get up the hillside, of course with A/C on it felt pretty good working with the 'ol girl' again.

Well FM I've got 2 x oil stains on my condenser so it's on it's way out. Only done 3 years and 15,000 salt free miles. The original one did 17 years and 131,000 miles in all conditions.

 

[frank rabbets]

Well I've bought a Toyota condenser and drier £360 all in. I'll let you know when it starts to leek, if I'm still alive .

I think the one I bought 3 years ago was about £150. Must be made of crap metal if there are already holes in it. It's only been wet a few times and has been garaged dry.
