1994 Mercedes SL320 Roadster... Radio - turns on and lights up but no sound

n/a
This started out as an intermitent problem....but now just doesn't work at all.
We have a SL320 Roadster and the radio turns on (everything lights up) but no sound....no sound from CD player & weather channel as well.
The power antenna does not go up and that's a sure sign that the radio won't make any sound.
It doesn't seem to be sending a signal from the radio to the powe antenna & amp in the trunk.
The only thing we have done so far is check to make sure all connections are intact...which they are.
Any ideas?

84 300sd Throttle Linkage Adjustment

Does anyone have any tips on how to adjust the throttle linkages on a 300sd? I messed up the tie rod that sets the idle the last time I removed the VC to adjust the valves, I want to bring it back down. While I'm at it, I'm hoping to find out what all the other linkages on the valve cover do and see if I can give the car a little "tune up". The tranny hasn't been shifting quite right after I messed up the idle too.

1977 240d Brake pedal hard no travel

I have a 1977 240d The brake pedal has gotten hard to push over the last three days. Now I cant press the pedal at all. I checked the brakes at the wheel and the all look fine. I checked the master cylinder but the fluid level looks fine. I checked the booster and there is very little vacuum on the line, Could this be the problem. Is there a certain amount of vacuum that needs to be on there. Also is there a way I can bypass the vacuum on the booster to see if this is the problem.Am I chasing my tail is there some other avenue I should look into. let me know

1980 300td wagon WVO Starting w/STC

Howdy. I'm considering installing a STC conversion to my 1980 300TD wagon, but have a few questions before I do so. When you are running on WVO with the STC 1000 and all the upgrades (Boost Pump, Heated Pathway, Heated filter), how does the engine not need to be flushed out with diesel before shutting down to have proper starting the next day.

SVO Fuel Conversion Specific Aid

1986 190d ran out of fuel!!!???

I ran out of fuel....Engine stopped...I added one gallon from spare can in trunk...car started with little difficulty...I ran over to refuel and filled up.
I drove with out incident for three or four days, but now it will not start. My advisor indicates fuel filter(s??) and strainer may be problem. I have verified fuel in tank and changed fuel filter at front of engine compartment, and still unable to restart. Where is other filter located??
Any help greatly appreciated. Thanks, JEB

84 300SD Vacuum Question

Hi, I recently noticed that my transmission was having one of those downshifting noise when coming to a stop. I Checked this great site and found out that it was a vacuum leak issue. I checked the engine for any thing unusual and I found the vacuum line connected to the green "port?" was indeed disconnected. Connected it back and the tranny had the downshifting issue for while but goes away eventually. Drove the car today and I noticed that the downshifting "clunk" only happens when the engine is cold but shifts fine after the engine is warm.

1977 300D Transmission identification

I’m trying to identify the transmission model in an early production 1977 - 123 - 300D? The transmission has no vacuum lines running to it only electrical wiring (driver side) and a mechanical connection (passenger side). The car has been owned since new, so it’s the original transmission.

VIN# 123 130 12 019871
Eng# 617 912 12 006662
Trans# 123 270 0701 006832

'85 300TD why sudden rear braking ??

This is a new one on me...I just bought another W123...and after the second real drive for any miles..I heard a noise in the back the sounded like a cable wrapping around something...then the right rear wheel locks up...then lets go. My kids were 15 miles behind me, so I pulled over. We assessed the situation and the noise was coming from the right back wheel....clank, creak, clank at slow speed. I thought it was a CV shaft falling apart or the parking brake drums, but it was from the wheel area. But, the rotor still looks good on the outside.
