Merry Christmas, as applicable, to all. Bo

This is almost certainly your problem: heater/AC blower stopped working - Pontiac Solstice Forum

EDIT: OR, you said temperature control (not fan control). Then, it maybe this: http://www.solsticeforum.com/forum/f...-issues-54741/

I got the error code again today. Gonna reset and wait again.

I'm ashamed that I didn't initially remember how a solenoid works! I retired from that technical stuff 6 years ago but have done it since I was 14 and should have remembered.

The solenoid is indeed a coil of wire whose failure mode is USUALLY a short (0 ohms) or an open (infinite ohms), As someone noted, the plunger that is supposedly pulled by the voltage on the coil may or may not make its full travel if it is sticking.

So, I'm guessing the error code is tripped by failure of whatever FUNCTION the solenoid is supposed to do, and not by a resistance reading or the position of the plunger.

Conclusion: Should I spend $36 times 2 and change them both?

For $36.00 yes, I would do both.

Do to this post and TS I started a new book.
Name Codes.
To help someone in need. Like me.
I have been PNT out all the codes we have been
having. Inc my own that I cause.
Thank you JohnRR for doing the PNT.

The solenoid valves in question change their respective cam timing when they are actuated. Each has an associated sensor that provides feedback about the actual camshaft position. There are actually several possible failure modes, and any of them will result in the same fault code(s).

1) The wiring could be faulty.
2) The solenoid coil could fail, either open or shorted.
3) The solenoid valve spool could be stuck.
4) The oil flow to or from the valve could be blocked or inadequate.
5) The camshaft actuator could be stuck or broken.
6) The position sensor (or its wiring) would be faulty.

Yes. I would (and did) replace both solenoid valves.

Done. I have ordered the two solenoids from buy-oem-parts for total cost of $82.
I want to thank everyone for all the information.
Next time I'm in for repairs I'm going to ask to see how much $$ I saved.

May next year be even better than this year for all!

A pair going into stock.
Great post.

I also have an 11 code ,,plus 700 / 2637. Did that fix the problem? do you have the part numbers of the solenoids.

Checked both, 12.7 ohms and 13.7 ohms looks like I'll be replacing both.
