Hi again All

Today interesting thing(or a problem?) happened with our olds.We were cruising with the AC on(it was an automatic electronic one and it was in auto mode while blowing little cold at that time).Then we came to our home and entered our apartment garage which was in lower floor under the apartment.
After one or two minutes the AC fan started to blown full cold but not from side vents.It was blowing from lower vents under the seats and little blow from lower inside part of windshield(the vents that after the top of dash).We assumed that it was from the temperature change first but when we tried to shut AC off by OFF button it did not close!
All other buttons on AC was working except the OFF one.When we tried other functions on AC they were fully functioning with plus that full blown from under seats.
Then we tried to shut off the engine and this time despite the electricity is gone in car that full cold blown continued from under the seats and from lower inside part of windshield... we waited for sometime but that blown did not gone off so we had to took off the one cable of battery to totaly cut it off... after that we did not took on the battery cable again we will look at tomorrow...
What you guys think is the problem? a shortcut or loose cable or something? or it seems as the wire and electric system?if it not gets better tomorrow we are thinking to ride the olds to some auto electric service... thanks and see you in other AC maintenance topics because i fear from these electronic controlled AC's can get control over the car someday

well, thats an interesting one... You turned the car off, but the blower motor kept running? weird! I would almost have said the OFF button didnt work on your electronic controller, but you said it doesnt even turn off with the key off! I have no clue, keep us posted on any progress!

Hi again,
Today we took on back the battery cable but as we hook it to one pole the cold blown started again but this time from side vents yes i said the AC controls and panel seems off but this continues... and other AC functions were also working if you open them plus with this strange blow... so we ride the olds to auto electric service...
and after some inspectionss oskar went to the little black box which contains ''Central Heatings Resistant'' or the ''Radiator Resistant?'' ... Briefly resistant of the main heating system(not the AC system) broken up the service said. The broken thing was the stone(i assume conductor material or crystal)of that little black box which also contains the radiator resistant... so he took that part to look for replacement from a part dealer... we dont know the real part of the name but i assume Radiator Resistant iss the corrent one? if we cant find it here i think we order from other sites again... thats all for now

yes it was blowing with the key and AC fully off ... so we stopped it by taking of the battery cable as i mentioned ... now luckily we found the source... thanks for your interest.. now i hope we can find the new part

Was the source the ignition switch?

no it was the blower/heater motor resistor! the thing that inside the black box which is under the plug connections of AC.. i finally learned its real name thanks god...
i looked for several sites but in alot of sites its saying you should get this part from Oldsmobile dealer ... is that mean that they are not selling this part like they sell other parts?
