I'll try to make this as clear as possible. I HAD a pristine 93 190E with 50K miles. It was totalled by a sideswipe from a semi. I purchased a nice body 92 190E and swapped the engine/tranny and all is well. Now I'm working on the creature comforts. The 92 had an aftermarket radio tuner (Kenwood) head installed which did not work when I bought it - the faceplate was missing. I wanted to keep it OEM, so I pulled the console, restored the wiring back to original including the original console fader, and installed the Alpine head from my 93, which was working fine previously. I know the wiring is correct, have done all the continuity checks, but still have two problems. 1: no audio - right side, and 2: power antenna does not work at all. Since the head was fine in my 93 (everything worked correctly, and I'm positive I have the wiring back to OEM with no errors, the only difference I haven't checked yet is the amp in the trunk. I thought the amp was for the door woofers only, and have not swapped this out yet. Can the amp cause my two problems?? Oh, and I have also swapped out the rear and dash speakers from the 93 too, which were all working as they should, so I doubt if it's the speakers. Am I missing something? Gilly, you have been spot on in the past with my questions, but this one has me stumped. Thanks; Don

For the antenna, check your connections at the switch and at the antenna itself. If all looks good, it might just be a bad switch or the antenna motor went. My antenna motor has went on me before. Also, check your fuses.

For the speakers, the amp only powers the door speakers. Did you check the fader switch to see if its slightly disconnected?

I would definately look into the fader switch most aftermarket installs in benzes bypass the fader. I would check to see if this is the case, it could also be that new speaker wires were run tot he speakers.

Sounds like quite a project you have endured to get back to what you had.

For the antenna, the easy way to test would be to make sure you have the right wire, make sure if the car has a dash mounted antenna switch that it is set to the up or auto position, and if that is not the case, check the antenna itself.

If the antenna is at fault it is most likely the relay unit for the antenna. or possibly the motor, and in some cases the mast is broken or the gears inside broke.

Thanks all for the replies. Yes, it's been a lot of work, but I really like the 190E and since I only had 50K miles on the old one I figured it was worth saving.

It's not the fader; I even replaced it with another - same symptoms. If I force the BALANCE all the way to the right and crank the volumn all the way up, I can I hear weak audio from the right side. Sounds like the head unit has gone bad - again. Was working fine before the wreck before though.

I have no antenna switch on the dash on either vehicle. On my 93 the antenna went all the way up when I turned the Alpine radio on and retracted when I shut it off. Probably the antenna motor has gone bad; I can take the old one off. Much of a job? Haven't done this yet so don't know where to start. Where's the relay, and is voltage or a ground applied to the coil to move the antenna? Sorry, don't have a schematic. Don

antenna is simple. rmeove left side of trunk interioe panel. undo not on top of antenna. undo bolt inside trunk on bottom and unplug the wiring harness and pull the sucker out.

Have you tried a different radio to see if that is the problem?

Is it possible that your 93 had 2 amplifiers not one?

Antenna problem solved but I feel like a jerk. Went to the garage where my 93 is with intentions of pulling the antenna off, looked at it, and it was slightly different. Some %&$*# had installed an aftermarket non-power antenna on the 92. Good reason why it didn't work. Thanks for the advice on removing the antenna - next weekend job - I'm tired.

Only one amp on the 93 in the usual place. Did any 93's have two amps?? I think it's the head unit. BTW, my 93 is in super shape, except for the drivers door and the roof is caved in. Gray exterior and interior. Lots of good parts. Email if you need something. Guys on this forum are the best. Don
