| ac codes f46 / f47
HI
I got a Fleetwood 1988 4.5l FWD, I retrofitted to R134a. I didn't do it by myself but by pros. Since then my AC doesn't work good. After replacing compressor that was leaking, accumulator, orifice tube, low pressure switch the bcm still throws codes and turns the ac off. I've already replaced the bcm by another one from a 1988 deville. But this one didn't work fine it showed the code f41. But I think my fans work fine.
But now to my problem. I've put the same amount of R134a as R12 1100g freon. After clearing codes the ac works for about 5 min then switches to econ. What can I do now to get my ac running. I'm trying now for 2 years to get it done. But somehow no one can make it right. Could the evaporator or condenser be the problem? Because the system is not leaking, the air blows cold. Help me in any ways. Thanks
Is it possible to retrofit this car in general? Any tricks to cheat the bcm or the sensors?? |
