climate control error15 and 09 - '90 90q20v

[Gaidos,A.]

 All,
Still trying to figure this one out. The climate control for my 1990 90q20v
is giving me both 09 and 15 on channel one of the diagnostic program. I'm
getting no heat at all.
 My understanding is 15 is the flap control motor for heat and 09 is for an
open at the temp control sensor. I'm guessing the temp sensor is at the back
of the head below the battery try with 2 wires coming out and is not the 4
wire multi function sender to the temp guage. Is this correct?
 Going to channel 06 to check that sensor I get something like this: -|55
which doesn't show up in the chart inmy Bently.
 Anyone care to offer their experiences?
Thanks
Anton

 All,
Last night coming home (in what is very cold weather for Santa Cruz) my
heater stopped working. Today I did a diagnostic on it and got the
following:
Error code 15. It then flashed to 00 but then back to 15. When I switched to
channel 7 I got 2, 6 and 7 for flap settings. Basically it's set for cold
air from footwell and defroster in recirculation mode (if I'm reading it
correctly).
 Anyone know a straight forward way to address this?
Thanks
Anton
