QuestionQUESTION: Hello, power door locks in-operable....checked the switch/solenoid in drivers door & it checked ok.
Haynes manual says there is ciruit breaker and a relay for the power locks & removed the drivers side & the passengers side under-dash panels, but cannot find either one [wire colors in Haynes do not match wires on under-dash relays].
Any Ideas? Where are the circuit breaker and relay for the power looks?
Thanks.
ANSWER: Hi Rick,
The ser. III XJ-6 had either solenoids or motors. The earlier cars had solenoids and the later had motors. The easy way to tell which you had was the sound. Each time you would lock the drivers door you would hear a loud "Clunk" from the trunk solenoid. If you had motors type(which I think you have) you would have heard nothing. (when they were working) Only the solenoid type had a "Lock Relay" and a "Unlock Relay" and a "Thermal Braker". The "Motor" type had no relay nor thermal braker. They did have an in-line fuse in the Aux fuse panel area up to vin # 470739 and a 15a fuse in the #17 fuse position from vin #470740 on. Each motor had only two wires which would lock in one polarity and unlock in the reverse polarity. (including the trunk lock) where as the earlier solenoid type could not unlock the trunk electrically.
The two systems were easy to ID by their appearence too. The solenoids were round and the motors were flat trapazoid shaped boxes. I hope this helped.

QUESTION: Howard,
thanks for the quick response, but here goes. I used to hear a load "thunk" from the trunk, and the switch/solenoid in the drivers door is black & rectangular, with a 4-wire connector attached[with 12v on one lead]. I found a in-line fuse at the aux. fuse panel [which is good and has 12v to it]. Does this info. help?
Again thanks for your time and expertise.
Rick [p.s. vin is under 459990].
AnswerIf you heard a clunk from the trunk when you locked the door it means you have the solenoid type locks. If any lock works with the key it proves that the "lock" relay in the right kick panel is working and that the fuse #17 is Ok and the thermal breaker (just right of the fuses in the Aux panel)is also ok. There is NO in-line fuse used in the solenoid type locks. To test the lock and unlock relays (unlock relay is in the left kick panel)
Disconnect the 4 wire plug on the drivers solenoid and with a test light check to see that the "Black" wire on the harness is a ground. The "Purple" wire is power. Apply 12v to the "Orange w/green" wire to lock the 3 doors and trunk. Apply 12v to the "Orange w/Red" wire to unlock the 3 doors. To test each relay apply 12v one at a time to each "Orange w/green" wire on the "C1" and "C4" position on the "Lock" relay to lock the 3 doors and trunk. Then apply 12v one at a time to the "C1 and "C4" position on the "Unlock" relay to unlock the 3 doors only. With these tests you should be able to isolate the problem.
