Hello i am new to the site, i have a 89 300e my wife drives 147k and lately she say's when she comes to a stop sometimes the car just dies, after putting it in park or net. it starts right back up no waiting??? also sometimes the a/c system goes dead ( no blower, compressor, and the pannel seems dead) after a while it will work just fine, has anyone had any simular type problems, any help will be great, thanks, Mark

It sounds like the alternator is not working right. Any lights? More symptoms!

Hi,

Could be two unrelated problems.

First, the engine dying could be from a loose vacuum hose. My car was doing exactly the same thing. A vacuum line on the back of the engine was so bad it fell apart when replaced.

Time to do some serious vacuum hose replacements. Do them all. It will save you a lot of headaches. Some you should do on your own. Breather hoses on the valve cover and the idle control valve. Do a search on the above. You'll get lots of advice.

As for the ACC control, sounds like a bad solder on the ACC control unit. How are you with a soldering gun? Let us know.

BTW, I had the same ACC problems with my car. Re-soldering the board worked.

Regards,

Thanks for the help, i will track down the vacume lines and replace, the a/c pannel you are refering to is the push botton pannel in the dash?. I am pretty good with a sodier gun, i used to own a jag ( lucas wiring) haha, the alt. seems to work fine no battery or light problems, thanks again, i will post after repair
