RE: thermoswitch 3-connector type

[pjrose@servtech.com (Phil/Judy Rose)]

Mark,
I had raised the issue about this type of switch possibly causing AC
problems. Others have responded to say they had been using the 3-terminal
switch for some time with no difficulties. However, my Audi mechanic stated
he has found that a large percentage of (the dozen or so) 3-terminal
switches he has installed have needed to be replaced because AC was erratic
or non-functional. He gave me a new 4-terminal switch which he believes is
still an available part from Audi (he's an independent, and if the parts
situation has changed in recent months, he might not be aware). I can't say
if the new switch cured my problem 'cause the AC decided to work fairly
consistently during the couple of weeks *before* I installed the new
switch. The temp gauge may be reading a notch higher now, though.

Soooo, the problem may not be inherent in the 3-terminal design, but rather
may just be a bad production lot of 3-terminal switches. Your switch might
be OK. BTW, the original (4-) connector fits both style switches.
