I tried the Armorall tip on my 93 Convertible. I bought it just this past winter and it had been neglected for quite a while. I had to clean a mouse nest out of the radiator. I thought I’d never be able to lift the hood in public (Without spending a fortune and a lot of time). I bought the Armorall and applied it the way Rob described. The wheel wells and inner fenders were especially grey and nasty looking, even after washing. I used a rag to spread the foam and things started looking better. Hoses showed an immediate improvement. The fenderwells took a second application before they showed any real improvement. The payoff was the third time for the fenderwells, and that was a week later. Now a quick touchup is all it takes to make things look really nice. The aluminum still needs work, but that’s wire brush territory. Thanks, Rob for sharing your tip. Now the underhood area looks as nice as the rest of the car.

@craig, sorry, he was a personal friend who is an electronics wizz -he provided the circuit diagram and worked out what nearly all of the parts are.

That info should help anyone with a little electronics knowledge fix the module.

More than likely it’s the large transistor, in the TO 220 case, they get hot when the doors are left open.

Mine now has a HUGE transistor there with large heatsink and I’ve had no further problems. I still am careful not leave the doors open when cleaning or fixing something without disconnecting the battery though. BTW I have seen mechanics leave the door open for an hour!!!

Hey Rob it’s Rob, This article was very helpful to me also. I was able to get my dimmer module replacement from a Corvette Parts web site in the USA. The site is looking good. I hope you get a chance to play your keys once and a while.

G’day Peter – I guess your vette is still LH Drive, that makes it so easy to get at the module!! When my module failed it left the heater fan blowing even with ignition off and key in my pocket.

I don’t know how else it fails.

If you disconnected the module and the fan stopped, it suggests the module is faulty but have you checked the factory service manual – the electrical section will tell you how the circuit works.

It’s extremely difficult to look after a 20+year old Corvette without owning the factory service manual!!

I would just mention that one night I leaned into my vette to get something and heard a short brrt, about 10-20 seconds later another brrrt – it was the power seat trying to move back, probably to finish an adjustment made earlier that day. When I move the seat now, I always finish by moving it the other way a few mm, to make sure the switch is off. I mention that in case your power draw could be something else.

Hi, I have an 86 corvette and i noticed that after a couple of days of no usage, the battery was drained sufficently enough not to allow it to start, unless i jumped it. After many days of searching and unplugging things, and re-plugging and removing bulbs etc etc, i finally disconnected the blower fan module (that you have at this picture http://robhealey.com.au/Corvette/wp-content/uploads/hvaccontrol1-600×450.jpg) and finally joy, the amps that were being drawn, stopped being drawn. now i bypassed the actual blower with the meter to find that something before the blower is causing the draw of amps. so i am assuming its either the module, the ECC inside the car, or something else. any ideas? or any ideas on how to test the module? (its a 6 pin module). I live in the UK so its not quite so easy to pick up a new module to replace it and thus expelling the module as the problem. Cheers in advance

@Blake – more than likely the Transistor in a TO 220 case is faulty – as pictured – they get very hot. Try replacing that.

All the info I have is here.

The other alternative might be to buy a dimmer kit from an electronics store like radio shack – must be 12 volt and able to handle say 4 amps to be safe.
