Hi. Have you anybody retroffited ptc with manual AC? I retrofitted ptc(exactly by guide) but ptc doesnt work :-( . Always I saw ptc combined dual AC.

Thanx for reply.

I retrofitted the PTC heater system to my Focus MK2 with manual A/C.

 

For the PTC heater system you will need a different type of heater control panel which has an additional microswitch (and some components) on the circuit board. The standard heater control panel does not have this microswitch.

 

The GEM module/fuse box also needs to be suitable for the PTC heater system and after installing the PTC heater system it needs to be activated into the GEM module and the instrument cluster.

Yes yes, I know about the microswitch. I havenefficiency´t the circuit board with microswitch, but I have extra manual switch, whitch gives an information to the GEM. I have activated the ptc in GEM and also in instrument cluster. BUt I still have the fault B2976-0F :-(  When the switch is switchen, On instrument cluster I see xy% of efficiency ptc but still havent warm air :-(

What do you mean "(and some components)"?

 

Sorry for my enghlish  :oops:

There are different ways of activation depending whether you have manual or automatic AC

If instrument cluster displays % then most likely you have activated as for auto AC

The circuit board of the heater control panel suitable for PTC heater has an adittional microswitch, some extra resistors and a transistor. It is not only the microswitch which is missing on the standard panel.

 

 

Does your GEM module actually send the PWM signal to the PTC heater? As far as I know some GEM modules with lower options are not suitable to control certain options because some parts/components on the circuit board are missing. I have got a MK2.5 GEM module in my car which supports all possible options. With this GEM module the PTC heater is fully functional. I tested the PTC heater also with my original MK2 GEM module which obviously does not support all options. This GEM module sends a signal to the instrument cluster but does not send the PWM signal to the PTC heater. The result is a message on the display of the instrument cluster about the PTC heater being active but the element not being activated by the GEM module.

I think I have higher version of GEM, I have xxxx-xxxxx-DE version. Now I am hunting for the The circuit board(with some next components), because I am really frustrated yet(its the finally step what I think where is the the fault nad before ptc damaged)  :(

BTW, today my car visited the service station(ford service) and they said, that in the datalogger the the signal is OK.
