So...Here we are, cruising down the highway and enjoying an unseasonably warm
afternoon with the top down( '90 C4 Cabriolet). Everything is purring along just fine,
and then we "bumped" a high spot in the road expansion joint and the cabin fans come on by themselves.I did not have the fan switch on,nor did I have any of the
accessories energized.The strange thing is that I have been trying to figure out why
I can't get the cabin fans to come on with the air conditioner or the heater...
I bought the car that way about a year ago and can only get the fans to function if I jump out connections at the amplifier mounted on the large aluminum heat sink mounted in the front "trunk" stowage compartment. All fuses,relays and resistors are good, and as far as I can tell the plug-in connectors are functional.
The question: Why did it come on when we hit the bumps(stayed on for a few minutes the first time we hit a bump and again when we hit another bump)then stopped.I never had cabin fan control via the dash switch...just never worked.
The a/c compressor works and the system blows cold air when I jump out the cabin fans and get them blowing.The rear blower in the engine compartment works,but then again,only when I jump it out.
I would LOVE to get the system "functional" againg so that when I sell this beauty
some Idiot will not try to beat me up over sale price!
Any help will be greatly appreciated!
Much Thanks!
Tony
