Well, ever since I bought my '92, it would run past 200* even with the 180* thermo, and the ECC display would flash. Well, today I noticed that my "High speed fans" for the AC weren't so fast. I KNEW it wasn't right, as it seemed it was defaulting to the low speed relay, so I proceeded to switch the low speed relay and put it on the high speed connection. Well sure enough, reached in, fired it up, flipped the ECC on, and flipped the redneck AC switch on, and BAM! I got high speed fans, also another odd thing, the ECC was no longer flashing, AND now my temp stays near a solid 180-185* now according to the gauge. The other fan relay that was dead is on order, so I will have a low speed for the fan again. Crazy how one little relay could cause such a fuss.
At least I can rip that stupid redneck AC switch out now.
