Hey Jamey,

Speaking of smarter, not harder, what do you think of this one?

'95 Caddy, won't turn off the SES light until 'idle relearn' is completed.

AllData gives me a nice procedure, all spelled out, BUT ... the A/C must be active during several parts of the procedure, and this A/C is inoperative, from a refrigerant temperature sensor code.

Sensor is open ckt, but a brief half-twist revealed that it's in the refrigerant stream, and the refrigerant is severely contaminated with dye and sealant!

Advised customer that we can't clear the light until he finds someone willing to risk their equipment dealing with the A/C mess!

Much bitching and yelling ensued. After all "all he need is a mother f*****g smog!".

Oh well,
