I bought this car in June 1909 from a dealer. Looked very smart, but the heater was not good on purchase, nor even after a new thermostat and radiator. I was advised to change the heater matrix, I did so, then it gave no heat at all. Both hoses to the matrix get hot, but heater gives no heat. I bought a Vectra 1.8 estate May 2020, e-bay auction purchase, car in daily use, no faults to date.
A car with no heater is no use in the winter. I have changed heater matrix, radiator and thermostat. I gather from Haynes temperature is determined by flap valves. I presume mine do not move as they should. On removing the glovebox I can see a pink lever moving on turning the large temperature control wheel.
Question is: can I rectift the fault, so that the heater prduces heat? If so, how?

For 1909 above, read 2019.

Does the other end of the pink lever do anything?

does it have air con ?
have you checked to see if it has a heater bypass valve like an omega ? older vectra B ones did :-\
i've never really done much with vectra C
i imagine the only thing left is the flap actuator but you'd need to match part numbers
remove the actuator and see if the flap moves manually and see if the actuator moves separate ,when not connected to the flaps (but plugged in and switched with the controls)
not a job i've ever done ,other than the recirculate valve on astras

No hbv on the Vectrum ;)

OK thanks DG :)
so he has a problem with his flaps then ;D
actuators on ebay clicky (https://www.ebay.co.uk/sch/i.html?_from=R40&_trksid=p2334524.m570.l1313&_nkw=vectra+c+heater+Actuator&_sacat=0&LH_TitleDesc=0&_osacat=0&_odkw=vectra+c+heater)
seems to be 3 ? probably all different part numbers depending on what they do ;D

Don't forget there are three types of system...
Single zone aircon
Single zone climate: Design and option
Dual zone digital climate: Elite/Plod and option

that would imply I knew something about Vectra Cs in the first place ;D
which I don't :-[
I drove carltons for 20 years ,the "air con" was whatever air came through the rust holes DG :D
just trying to help Terry out with my very limited knowledge of the basics .
Terry,
what trim level is it ? so we can work out what flaps you may have
though manually operating the flaps and testing the actuators might show what's wrong
have you tried the selector in different positions on the heater panel ? to aim the heat at something other than the screen :-\ like the footwells. also.... did you put the trim panels etc back round the matrix so the hot air is not just leaking out there ?

Trim level is SRI. I have tried it in many settings, now no heat anywhere.
This morning I took out the glovebox, then it occured to me seeing all your pics of motors that the fault might be electrical so I checked all the fuses. Sadly nothing wrong there. My thanks to you and Doc G. I shall persevere.
