#PIC4547: XLR Roof Does Not Latch At Rear Corners In Stowed Position - keywords latch loose mid open potentiometer retract stow trunk - (Jun 13, 2007)

Subject: XLR Roof Does Not Latch At Rear Corners In Stowed Position

Models: 2004-2007 Cadillac XLR and V-Series


The following diagnosis might be helpful if the vehicle exhibits the symptom(s) described in this PI.

Some customers may comment of a mark in the paint on the roof panel. This mark may be on the drivers or passengers side of the roof and typically the size of a pencil eraser. Further inspection of the retractable roof may indicate when the roof is stowed, the rear corners of the roof are not secured in trunk area. This may be the result of a misadjusted roof panel.

Lower roof into trunk as far as it will go. Stop when trunk starts to close. Check to see if the rear roof latches engaged the lower support.
Scribe the current position of the rear roof panel pivot bracket bolts. (See Attached Picture). These marks may be needed if the panel moves more than needed. The position should only change about .5 mm (one half mm).
Loosen both of the rear roof pivot bracket to rear roof panel fasteners one turn (both driver and passenger sides). These only need to be loose enough to allow the bracket to slide under the bolt shoulder. Do not allow the shims (if present) to become mis-positioned.
Manually lower the panel so the rear latches engage and latch. Lightly bump/thump the rear corners of the roof panel above the latches using your open palm.
Re-tighten the previously loosened fasteners to 18 Nm or 13 lb ft.
Cycle the roof and ensure that it latches properly in both the up position and down position with out assistance. If it does not latch in the up position the strikers can be adjusted.

(1) Front Of Vehicle

(2) Loosen One Turn

Please follow this diagnostic or repair process thoroughly and complete each step. If the condition exhibited is resolved without completing every step, the remaining steps do not need to be performed.

Properly trained technicians have the equipment, tools, safety instructions, and know-how to do a job properly and safely.

Just got a 2006 and have question

I know this is an old one, but I'm a newbie and have a question on this one.
I did notice a couple of small paint marks on the roof (both sides) of the 8,000 mile 2006 XLR that I just bought.
Do they still warranty this or is it customer pay (out of factory warranty)
Any information would be helpful, thanks

Your dealer may fix this as a goodwill gesture if the vehicle is out of warranty. Otherwise see below and have it painted.

After doing the alignment procedure, there are two threaded fasteners that protrude from the underside of the rear decklid brackets that have the potential to contact the top of the roof if it isn't laying flat when in the stowed position. They should be ground off to be flush with the retaining nut with a Dremel or similar tool and the area covered with plastisol or RTV to protect the roof afterwards. This is documented in earlier posts. I did it to my car and haven't had any issues. This is easy, quick and free if you have the tools.

Hey the car is new to me also. I have only put the top down twice. I noticed a mark on the roof on driver side about 3/4 the way back on the roof about where the window ends and about 2" in. I've read about the adjusting and yesterday prior to putting the top down I checked what could of been making the mark. When the top is stowed away I started to lower the trunk and thought the screw end that has the torx's end on the underside of trunk lid was the culprit so I grinder a little off. Drove around a little popped the trunk and saw paint on the actual bracket that you see on the underside off trunk on the driver side. I did not check to see if the top is being secured like stated above but I will. Is their any adjustment that can be done by a skilled mechanic (me) without throwing the top out of wack. The post above said there were pic's I didn't see any. Any info would b awesome thanks.
