A/C temp flashing...code -152

[vhandobi]

I had my AC temp flashing. Looking in these forums, I found how to enter the diagnostic control and reset the unit (Based on the fact that when this error occured my AC would go from AUTO to ECON and only be fixed by disconnecting the battery.)

When I entered diagnostics, the only stored code was -152. Where can I find these code descriptions? The scan tools do not pull codes from the Climate Control as far as I can tell? I'll see when it gets a little warmer if the reset fixed my problem. Thanks.

I forgot to mention that I have a 92 Lesabre Limited with Electronic (digital) climate control

I believe a code 52 is a low freon code. Turn your AC on and see if it goes to auto, if you have low freon it will go to econ. 99% of the freon leaks I have seen have been the evaporator core leaking. If you remove the blower motor resistor on top of the HVAC case look inside if you see junk covering the fins of the core it is leaking.
