[xj-s] TOPLESS in Seattle

Hey mates…brought home a gorgeous 1993 XJs convertible
yesterday. Jade green with lighter jade interior. Checked all
systems prior to purchase…opened the top/closed the top…all
went fine… open the top and drove home…top will not go back
up. Have attempted to find fuse for the top…still dont I
have located it. wondered if anyone knew where this was
located…then I will go to the switch and so on. There is no
noise come when I mash the convertible top button…in either
direction. Any thoughts? Thanks–

First, make sure gear selector is in Park AND that handbrake is fully
set. The top motor circuit has safety switches for both handbrake and
gear selector to prevent unwanted sailing.

The Electrical Guide shows an inline 30A fuse in the “Luggage Locker”
near the Top Motor and ECU.

I don’t have a convertible, but it is my understanding there is a
disconnect in the connection between the motor and the top unit which
can be utilized to manually raise the top, if say it should actually
rain in Seattle and your motor won’t do its job :wink:

Usual thing with new owners is they do not read the owner’s manual.
( That goes for me too ).

To operate the top gear shift must be in PARK, and HANDBRAKE ON.
Ignition must be ON, or at least in ACCESSORIES position or something.

Otherwise the top electrics are inhibited.

“Topless in Seattle” sounds like a good title for a movie.

I have a 1995. Same problem when I bought it. There are relays
above the battery in the trunk. Very easy access and replace. There
are 6 relays involved in the operation of the top

From left to right facing the front of the car:

  1. Left quarter window down (white base)
  2. Left quarter window up (yellow base)
  3. Top down (blue base)
  4. Top up (green base)
  5. Right quarter window down (black base)
  6. Right quarter window up (red base)

If the hand brake is up and on, and the top does not go back up,
swap the two middle relays and try again.

Then go out and replace at least the top up and top down relays as
a precaution.

The back right rear window on my 95 XJSC will not go down when I
put the top down. I wanted to check the relays before trying
something more invasive. After reading the topless in Seattle
thread, I checked the relays above the battery. I seem to have 7
relays and a 30 amp fuse. Does this configuration conform to Henry
NYC below? If so, what is the 7th relay and fuse for? I am hoping
to get a owner’s manual for my birthday.

Thanks, JS 95 XJSC

JS,

You can see a wiring diagram online. Go to
http://www.captainjaguarscathouse.com/Electrical_Reference.htm

Download the 1995 XJS Electical Guide and look on page 11.

Thanks,

top was working fine until I got home and tried to raise it. No sound from the pump. Rear windows work fine after the 8 second delay. exchanged the relays and all are working. Moved all the wires around in case of a loose connection. Still nothing. What should I try next? Thanks in advance. Have had the beautiful jade green for 6 years so am familiar with most of the top workings.

Just put the top up manually and moved gearshift to N and P a few times and the handbrake a number of times and still no sound from the pump. NEED HELP:)!

Fred,
I would check the fluid level in the convertible top pump reservoir and make sure it is properly serviced. If the fluid level was OK then I would bypass the automatic features of the convertible top and power up the pump directly to verify if you have a pump problem or an electrical problem.

Paul

Thanks Paul, The pump fluid is fine, just not getting electricity. Will take apart the switch on the console and see if that does anything. The rear windows do work so I’m thinking the switch is ok but I’ll clean it anyway.

Fred,
A test for a failed pump should be relatively quick and easy to do but sorting out an electrical problem will likely take much longer. If I were you I would test the pump first to determine whether or not it has failed. If the pump works then sort out the electrical problem. If you start looking for an electrical problem first and it is actually a failed pump you will have wasted a lot of time.
Pumps can fail, but I suspect that it is likely an electrical problem in the overly complicated automatic convertible top system.

Paul

Hi Paul,
I’ve had a lot of experience with the pumps and have even taken them apart. Do you know if there’s another fuse besides the one next to the 6 relays in the trunk?

Fred,
What year is your car? I am very familiar with our 1990 XJ-S convertible but I know nothing about the later facelift cars except that they are very different from earlier cars in most every way.

Paul

Fred,
That 30A fuse is the only fuse in a 1990 XJ-S convertible top system. If your car is a 1992 or later I have no idea and it might be different.
Attached are pictures of the pump and hydraulic pistons that recently removed from my 1990 XJ-S convertible parts car. When I applied power to the red and black wires to the pump motor the pump runs and the pistons move.


This simple test should prove whether or not you have a pump problem. If the pump runs like this one did for me then you have an electrical problem, which is most likely in my opinion.

Paul

Had that problem once. The culprit was the switch on the handbrake,
