My heater doesn’t seem to work. How can I fix this?

There is a control valve in the engine bay. The correct replacement can be sourced, but is relatively expensive.

You can replace your old VSV with Toyota part # 88690-32280. It's from a Camry (I believe) and is virtually identical to the original stock one. Only thing you'll have to do is cut off the leads from the old VSV and attach to the new one with solderless connectors. Again, follow the previous article to see how to do this. The new unit comes with a bracket that you can discard, and mount the new one to the stock heater diaphragm valve just like the old one. Oh, and it only costs about $70 (2001).

The $ are Oz so = about £30 tops.

To find these answers and more look using google.com and put in ALSC or whatever!

Happy hunting.

Oh and don't forget www.toyotaimportsforum.co.uk for a very active UK based Soarer mad forum. Soarer Sanctuary is the place to get stuff done very cheaply but its dahn sarf!
