Old Climate Problems

[Simons]

Hi,

I have a problem with an old 3b climate, when you put the contact on, works, after 2 seconds die...no lights, nothing...if you put the contact off and on again, the same, 2 seconds working, the unit remember what you select the time before (if it was showing outside temp. starts again with outside temp.) and then nothing.

I test the fuses and with another display unit and the same

I take a look at the schematics and I don't know where is "J127", maybe it's under the dash, the unit who has the coloured vacumm hoses??

Any ideas about the problem??

P.D:Thanks s2central

Yes It is.

Thanks mate

I have another clue...When the climate dies, the back light switch for fresh/recon air loses intensity

Check the resistor unit ontop of the fan.

Finally was a bad ground, pin 7, I ground it with the radio cd and fixed
