The heater blows hot in any position, heat..AC...vent...defrost...etc.
When I dropped the glove box door and reached in I felt wires at the
back of the temp gauge.  Is this control a rheostat that controls a
water valve or door?  Or is this the blend door problem that I've seen
a couple of posts on?  My MAX AC door vacuum solenoid has been broke
for quite some time and I've been getting along without it.  I'll
Google it but I thought maybe someone here might offer some advice
before I tackle it this weekend.  It's a 97 XLT 6 cyl. w/AC.  I still
luv my cherry Explorer but lately its been nickel and diming me to
death with all the plastic parts around the engine breaking.

Thanks in advance....
