Sounds like you have a flaky ground.
If you can see it via the radio hole there is a ground star that may have things iffy on.

There is also an issue with the ground wire on the heater motor blower harness left side of the heater box
high a white or yellowed connector that if the ground pin is burnt, 3 cabbys had same issue.

I would test the heater switch all the wires are 12V.
well the main is black/red fed from f14 area.

Radios that don't work are bad power or bad grounds.
If the radio comes on but doesn't have any sound then that is a speaker wire mismatch or again ground issue to the speakers.

I replaced my Aktive and the Premium in both my cabbies with JVC Bluetooth aux media players, had a dickens of a time with the aktiv as the POS hacked and butchered the wireing.  My 93 Premium was painless as I bought the connecter kit from soche, and it was plug and play till the door speakers bit the wienie.

Take the earth lead off your car battery when working on electrics and pulling wires from the dash, saves you blowing fuses etc.  

Thanks for both replies gents i should have known better .im out of my depth with electrics. Mark your right i totally forgot about disconnecting the battery a school boy error clearly .and brian i appreciate your answer but again its not my realm .so thanks to you both .ive got an appointment tomorrow with a specialist who can hopefully sort it .did check the fuses though and one was blown replaced it but still the heater wont blow .il let you know how i get on tomorrow. Thanks guys .and ps wheres all that gorgeous sun gone 😎

Ps brian my door speakers are rubbish did you replace them ? If so what with

Depending on what door pockets you have and speakers fitted, later cars have bigger front speakers but I fitted these to my 1988 cabriolet.

lots of places sell them so shop around, I paid £30 for mine but I’ve seen them for less and more money on eBay etc.

Nice clear sound but with the rubbish design by VW the front speakers are never going to be great that low to the floor, they do lack bass but I've a amp and sub in the boot which makes up for that no problem.

Later cars have this type of door pocket/speaker.

Early cars have this type which the speakers in the link I posted are a direct replacement.

Hi thanks mine has the black and red sportline interior with the door cards to match its got like little 2 inch square speaker covers about 2 thirds up the door are they not standard then ..thanks for the links the alpines look good ..thanks also ive heard theres a guy on here that lives in haslingden lancs if there is wouldn't mind making contact with him im only about 5 miles away 👍👍

Hi just a quick update went to a Halfords today seemed the cheapest ..great guy named steve explained that someone had taken the live feed for the stereo from the heater blower .hence when i disconnected the stereo i disconnected the blower as well .guy sorted it i now have tunes .and a heater 👍👍

Good Job,  I remember my 90 Cabriolet, and I forgot to turn the radio off at the airport, I had the volume way down…..

Drained the battery, and well being a EFI engine, no push and pop the clutch would work….

I used the Demister switch as it is a switched power place and easier to get to.

remember what Smokey the Bear say's if you forget to be mindful of power and grounds.
