* Under the dash: This is a common location for relays, though often requires partial disassembly of the dash to access. Look for a series of relays and modules near the HVAC system.
* Within the HVAC control module: The blower motor control could be part of a larger module. Accessing this will likely require professional help, as removing and disassembling the climate control unit is a complex job.
* Under the hood, in the fuse box (less likely): While less common for the blower motor relay specifically, some Cadillac models place relays in the under-hood fuse box. Check your owner's manual or a repair manual specific to your vehicle's year and model.
To find it effectively:
1. Consult your owner's manual: This is the best starting point. The manual should have a diagram of the fuse and relay locations.
2. Use a repair manual: A Haynes or Chilton repair manual for your specific year and model Eldorado will have detailed diagrams and instructions.
3. Online forums: Search online forums dedicated to Cadillac Eldorados. Someone might have already posted about their experience finding the relay.
4. Professional mechanic: If you're uncomfortable working on your car's electrical system, taking it to a mechanic is the safest option.
Without a visual inspection aided by a repair manual or diagrams, precisely pinpointing the blower motor relay's location is difficult. Be cautious when working with electrical components.
