Guest djsonarm Posted January 29, 2012 Share Posted January 29, 2012 Hi all, hope someone can help. I bought a Escort Calypso MK7 yesterday - a good little deal, I think. Low mileage, looked after, although apparently the roof didn't work but could be operated manually easily... I got it home and checked around the net a little re potential roof issues, as O heard you could prob pick one up on ebay for £70 and the thought of having to manually open the roof didn't bother me too much. Out of interest, I thought I'd see if the motor actually worked first - it did. We played around with the 'tap' and found that closing the that allowed the pump to open and close the hood. Result! Cheap car with a working roof as a bonus! Then I noticed that the motor stops about half way thru opening or closing. The roof and won't budge again - it doesn't move at all (doesn't even try) for a good 10 seconds or more. Then, a few moments later it'll work again. Sometimes for a couple of seconds before it stops, sometimes it'll go the rest of the way. It's almost like something you'd expect when something overheats and won't work until it's dropped to a workable temperature again - like a hairdryer cutout would work, I guess lol. Checked fluid level - in the middle of the two markings. I've checked over a lot of posts but nothing really answers my questions on how to fix this or what the problem might actually be so thought I'd post. Any help or advice would be truly appreciated on how I can get the roof working properly, as it seems to be a waste if it's very nearly working as it should after paying aprice where it supposedly didn't work Also, what is the 'tap' exactly? Is it literally something to 'engage' the motor with the roof so you can mannually use the roof if the electrics fail? Quote Link to comment Share on other sites More sharing options...

allblue Posted January 29, 2012 Share Posted January 29, 2012 (edited) Hi, The tap is the bypass valve that allows you to open and close the roof manually should the pump fail. Closing the tap seals the system, thus allowing the hydraulics to function as they should. Areas to check: Hydraulic rams behind the rear cards, leaks from the seals, etc. Roof frame to ensure in is not bent. The plastic cog inside the pump (known to break) Edited January 29, 2012 by allblue Quote Link to comment Share on other sites More sharing options...
Guest rosscando Posted January 30, 2012 Share Posted January 30, 2012 Thanks for that Allblue but if the problem is the hyraulic rams what should we do? can they be fixed or is it a case of replacing them? Quote Link to comment Share on other sites More sharing options...
f40 cab Posted January 30, 2012 Share Posted January 30, 2012 when did you check fluid level roof open or closed? what roof is it vinal or mohair? and as said earlier tap shud be closed. Quote Link to comment Share on other sites More sharing options...
allblue Posted January 30, 2012 Share Posted January 30, 2012 Don't think rams can be fixed, but check out the other points first and rams last as you have to take the rear cards out to inspect them., Quote Link to comment Share on other sites More sharing options...
Guest djsonarm Posted February 1, 2012 Share Posted February 1, 2012 Hi all, thanks for your responses so far. It's a mohair roof and the motor doesn't seem to struggle moving the roof, so I'd imagine it's frame is not bent. I'd imagine that'd sound like the motor is struggling in parts, but it doesn't. It literally just cuts out, not grind to a halt. Also, if the cog is broken, would that sound like it's struggling also? Or even not move the roof at all? Would it be the cause of a sudden power cut-out as it seems this is how the motor reacts when in use. I'm not mechanically minded so apologies if I'm wrong on the above. Does it still sounds like they could still be culprits and I should still be checking these? Also... The fluid level was checked with the roof closed, as far as I remember. I've read that a 'thermal fuse' may be an issue. Could this also be the case? How do I check the rams? I'm not sure what (let alone where) the rear cards are - automatic roofs are very new to me lol. Sorry for such basic questions. I haven't a clue when it comes to cabs. Thanks once again for all your help so far. Quote Link to comment Share on other sites More sharing options...
f40 cab Posted February 2, 2012 Share Posted February 2, 2012 if your saying it doesn't struggle it just cuts out id be looking at checking for power at relays, switch, etc when roof is in operation, and see if there is a power cut halfway through. your rear cards are the inside trim pannels next to the back seats as in the front door cards. the bits with the window winders and speaker covers,(ie mk 4) if you take theses off you will see the hydraulic rams if it is cutting out you need to find if it is losing power or just strugling to go past half way. if it is losing power then we can look at reasons why. keep us informed with how you get on.

f40 cab Posted February 2, 2012 Share Posted February 2, 2012 just reading your first post you say fluid half way between lines when roof is closed, have you tried filling it up to top line, Quote Link to comment Share on other sites More sharing options...
thomasn Posted March 22, 2012 Share Posted March 22, 2012 There is a thermal cutout beside the relays at the pump, sounds like it is operating then cooling down after a few seconds then remaking. I had the same problem before, very annoying Quote Link to comment Share on other sites More sharing options...
