Default A/C and cooling fans quit simultaneously...

My ECC is throwing a code 48, which did this when the blower wasn't working. I wired the blower motor back up, and it worked fine for a while. Now it'* throwing the code again, working only on ECON, and the cooling fans do not run, either on low or hi. Engine temps almost redlined, and they still didn't kick on. I checked the relays and fuses, and they seem to be fine. Is there anything else I should check?

Let me clarify......no AC in auto, circulation fan only works on Economy, and neither cooling fan works in any mode?

It won't even go to Auto. Rest is correct.

That'* a sign of an ECC fault, and unfortunately, 93 was the last year for on-board diagnostics.

Is your display flashing?

****. Brainfart. Thought you had a 94. Too damn many cars around here

Techinfo, bud. Especially if your display is flashing. Sorry about that....I missed part of your post in the rush to answer a few in some slack time.

Clear the code. Mine does that once a year. You might just be fine.

K. I'll try that. I already knew that 48 was long term freon loss, but the freon'* fine. And it seems to throw that code when something electrical happens...I'll let ya know...

No, that will have no effect. The ECC has a keepalive memory feature. Use the procedure in Techinfo VERY carefully to clear the code.
