Hi All, OK, armed with the little data I could scrape up from the internet, I hit the local junkyard. I found an early 90's Caddy, with the hood lowered which is a plus, and the BCM was the exact same part. Its located under the hood, against the firewall, under a cover and under some...

Thanks Agent. I haven't replaced the unit yet. Interestingly, I tried gmpartsdirect.com and they don't have the original part or a replacement part number. Stopped by Autozone, just for the heck of it, they don't show a replacement part either. Funny how nobody has a reference to this part...

Well, went back to the chevy dealer with the new Delco part number 12484912. The <same> parts guy had one in stock, and the plastic part of the unit looks identical to what I have. The "electronic" piece looks different, but I expected that. It's almost the same size, a little smaller (both...

Thanks for the feedback. I knew $500 was way outta line. Started searching the web and it looks like this is a fairly common problem on all GM cars. I found a couple of interesting threads that this part is common on at least the Buick and Caddy. Also looks like the part may be out of...

Hi All, Anyone know how to test a blower control module for an '87 ? The blower motor comes on randomly, for short periods of time, while the car is just sitting in the garage. It'll continue until the battery is dead. I disconnected the power to the BCM (by removing the 2 wire plug) for...

Thanks Harry and Eagle for the advice. Well, my wife never ran screaming from the garage, so I'm guessing there was no mouse, (I stored the car at home; garage is attached) but hey, thanks for the thought! A check at the aldl (or is it asdl?) pins A&B with a meter shows 10.32k ohms and 5.02 v...

Hi all again, Well, the vette is still broken. I thought I'd check one last time before I have it towed to the dealer. The symptom is still the same, when I turn on the car, the primary radiator fan immediately comes on, the car will not start until the fan stops. While it was doing this, I...

Hi All, Assuming I need to replace my ECM (see my other post "87 engine quits") I've seen a number of aftermarket ECM's in the various catalogs and local parts shops in the $85 - $100 range. The local GM dealers want just over $200 for a Delco unit. Is the Delco unit worth the extra money...

Hi All, My 87 didn't come out of storage very well this year. I need some help. When I turn on the ignition, the cooling fan immediately starts running. The car will NOT start until the fan stops. Once it stops, the car starts right up. It may run for 5 minutes or all day, then just stops...
