90Q20V "thermister" problem

[TWFAUST at aol.com]

The CC in my '90 90 reads a very low outside temperature. The 20V list tells 
me I should test the thermisters and probably replace one of the two. Fine, I 
can probably handle that. But, I wouldn't know a thermister if I fell over 
one. Could anyone shoot me a pic, or a more graphic description than "located in 
the plenum" and "near driver's side headlight".
