Hi. I've got '92 155TS/8v with remus exhaust and squadra chip. Got a little problem with rearwindow heater and antenna amplifier- both are not working. I even bought a new relay for windowheater/timer, no help. It still burns fuses and doesent work. My radio signal is also very weak- so i guess that the amplifier is not working. Any ideas? Has anybody any suggestions for right size of tire? My car has intrax -45mm springs and sachs advanced shocks. I've got 7x16inch.rims with 205/50/16 et35. And even with two peple load on backseat hears annoying scraping. Is 205/45/16 any better?
I think the best solution is to fit a "traditional" radio aerial. My first 155 - one of the original widebodies - had a screen aerial which never worked well and I've put standard aerials on two of my 164's. You will note that the late 155's had proper roof aerials rather than screen aerials. By the way, I think the problem may have something to do with location.... I live in Scotland - not many transmitters!
PS The best way to spot breaks in the rear window elements is to get the window all steamed up (!) - the breaks get really hot and de-mist first.
