Convertible top started to go back and then stopped 6 inches from the widnscreen. Manually cranked it back to close and now won't work and the system keeps dinging all the time. Can anyone offer a suggestion?
The problem I've run into was mentioned in passing in this feed, but I'm not sure about what to do next. The roof on my girlfriends car is closed all the way, but the sensor doesn't seem to realize that and the ding ding ding is driving us up a wall. I tried to find the fuse for that particular sensor and pull it but had no such luck. I tried to find the push button on the roof to try and jam it closed to stop the alarm but had no such luck there either. Is there anything we can do to get that thing to quiet down? It seems like a form of Chinese drip torture!
Convertible top will not respond to the button for opening it up.
Still not fixed.
we just bought a 2000 volvo c70 ,,,,the convertible top goes all the way down but not completely so the hard part is straight up and stuck....then if you push the button for the top to go forward it only makes it too the front with about four inches to go but doesnt make it ,,it stops......bummed out...
the roof storage area on my c70 will not open manually by cranking with the tools supplied and will not open with the switch so how do you get into it
top wont go down
top locked in closed position but convertible light and chime alarm goes off incessantly when driving the car. dealership does not offer any definite options to diagnose and fix the problem.
My hardtop will go down but the car does not recognize that its down, and the warning sign say top is not fully down.
I also had this problem with the top stuck between up and down. Had to manually lower the top into storage area. During the manual closing, I noticed two small broken switches on either side that appeared to have broken off the lift arms. Took vehicle back to dealership, they mentioned nothing about micro-switches or potentiometers but rather told me that I would have to purchase both a left and right "tappet" that allegedly are broken, at a cost of almost $3,000. Then they would be able to determine what else would be required to "fix." I paid them to raise the top, lock it in place and disconnect the switch and chime so that no one would lower the top again.
top stops short about 4 inches from completed closure.
Micro Switch on Drivers side was broken causing a problem with the first phase of the top opening properly.
Switch to raise and lower roof is not working properly, and doesn't work at all after I had to manually close the roof. Now the alarm won't shut off when I drive the car, indicating the roof is still open.
I had one of the two potentiametes replaced and have had problems with it ever since ie: wont complete its cycle when putting back up so the light and ding sound is on. Also after the volvo dealer so called fixed the potentiameter the top doesnt work up and down complete
and wont fix it for me after I spent almost $1,000!!
2 things Convertible top went down won't come back up.
Change battery in car radio won't come on reading code when code is entered it still doesn't work.
