Question 1

How much does it cost to replace accessory delay relays on a Lincoln Town Car?

Accepted Answer

Parts start at $10.95 for the Lincoln Town Car. The relay itself is inexpensive, and because it typically sits in the fuse/relay box with no special disassembly required, labor is minimal — often under 30 minutes at a shop. Total out-of-pocket cost is usually low compared to most electrical repairs.

Question 2

Can a bad accessory delay relay drain the battery on a Lincoln Town Car?

Accepted Answer

Yes. A failed accessory delay relay that sticks in the closed position keeps accessories like the radio, power windows, or interior lighting powered after the key is removed. Left overnight or over several days, this parasitic draw is enough to fully discharge the battery, making this relay a common but overlooked cause of dead-battery complaints.

Question 3

How do I test the accessory delay relay on my Lincoln Town Car?

Accepted Answer

The quickest test is a simple swap: locate the relay in the fuse box, pull it out, and substitute a known-good relay of the same type and rating. If accessories behave correctly with the replacement, the original relay is faulty. A multimeter can also check coil resistance and contact continuity, but the swap test is faster for most owners.

Question 4

Where is the accessory delay relay located on a Lincoln Town Car?

Accepted Answer

On most vehicles the accessory delay relay is housed in the under-hood fuse and relay center or an interior fuse box, often located beneath the dashboard near the steering column. Consult the fuse box diagram printed on the box cover or in the owner's manual to identify the correct relay slot before pulling any components.

Question 5

Will my Lincoln Town Car run without an accessory delay relay?

Accepted Answer

The engine will start and run normally without a functioning accessory delay relay — it does not control ignition or fuel delivery. What you lose is the timed accessory window after key removal. Power windows, the radio, and similar features will either cut off instantly or not function in their post-ignition mode until the relay is replaced.

Question 6

How long does an accessory delay relay last on a Lincoln Town Car?

Accepted Answer

Accessory delay relays are solid-state or electromechanical components that typically last the life of the vehicle under normal conditions. Failure is more common on high-mileage vehicles or those exposed to persistent heat, moisture, or electrical surges. A relay that fails early often points to an underlying wiring or load issue worth investigating before installing the replacement.

Option	Best for	What you get
OEM Replacement	Owners who want an exact factory match with guaranteed fitment	Identical pin layout, coil resistance, and contact rating to the original — plug-and-play with no adaptation needed
Premium Aftermarket	Daily drivers and owners who want reliability without dealer pricing	Heavy-duty contacts, sealed housing for moisture resistance, and tested to OEM specs at a lower cost than dealer parts
Value Aftermarket	Older vehicles or short-term fixes where cost is the priority	Basic relay function at the lowest price point; adequate for low-mileage remaining vehicles but may have shorter service life
Heavy-Duty / Upgraded	Modified vehicles or those with added aftermarket accessories drawing higher current	Higher contact amp rating than stock, handles increased electrical loads without overheating or premature failure
