Question about Cadillac Eldorado

Open Question

I have a 1985 Cadillac Eldorado Biarritz convertible. The climate control and fuel data modules have gone out and the blower stays on high. What would cause this problem and what would need to be fixed or replaced and is the programmer linked in with fuel data module?

SOURCE: heater blower install for 1997 cadillac eldorado

The solution is more than likely a new blower motor. Replacing this blower motor is no small task. I am in the process of doing it, but there is so little wiggle room that I suspect that if a cadillac mechanic does this job, they will jack up the engine/transaxle to make room. The motor itself is not cheap either, a replacement Delco is well over $200. I will let you know if my new motor install works.

SOURCE: heater blower motor on 1996 cadillac eldorado

very tight but you can clear the engine just moving some spark plug wires and the vacuum controls (controlled units?) right in front of it. when you get the bolts off the blower fan housing and its free to move you just have to rotate it so the flat part can clear the rear valve cover. do yourself a favor and be sure to isolate the problem to the motor (and not the electrical connections or the computer disabling it for something rediculous like lack of a/c charge) as it's an expensive part for a little motor and worse (around 250 i think) if you need end up replacing the entire fan.

SOURCE: Location of the blower motor control module

The module is located in the ducting for the heater and is accessed from the passenger area of the front seat. I think it is just under the dash but you may have to remove the glove box. it is a rectangular item held in with four screws. and should have two connectors going to it. You have to be sure to get the right replacement if you r replacing it.
thanks.

SOURCE: 1997 Aurora intermittent blower motor

there is no resistor but it does have a digital fan control module located under the hood above the fan motor in the heater box. you will need to remove the plastic cover again the firewall.and the the module will be under the relays.

Fuses 6-7-8-9 are powered from the ignition key switch.
Fuse 4 is powered from the RAP relay number 2 in the relay box.
RAP is for retained accessory power - its the relay that keeps power going to the radio and things after you turn the key off and before you open the door.

Fuel Data Center and Electronic Climate Control not funtioning


This is defenetly the BCM, I had a 1990 with all of the same problems. Buy a rebuilt and install it behind the clove box. Remember that you must install you memory prom into the new unit as they don't come with any in them (it is what is memorizing your miles driven.) You will get off pretty easy on this one as they are available and not too expensive.
