The age must have taken its toll for ur stereo, if u try to make that cassette stereo to work again, u will pay somebody, the cost could be just like buying a new model w/ cd player in it!
The rubber belt of the cassette could be at fault and the display for the temp and time might have disconnected inside.
Hope that enlightens u up!

If you hear the sound of the electric latch switch, then it's working but stuck somehow. Just put the key in the switch and turn it to the right and then pull up the trunk or ask someone to help you. it will open. I tried it today and it opened with me. It was stuck from inside by some kind of a broken plastic pieces. Just removed it and now it's working fine. good luck

Hello and welcome to FixYa!

As a first course of action, I strongly suggest that you have the battery charged. It can be an indication of a weak battery or a faulty alternator. If the battery light still on after charging then the problem will surely be on the alternator itself. If that's the case the alternator should be replaced to resolve the problem.

You may try to reset it to by removing the positive battery connector, letting it sit for at least 5mins. then reconnect it again. This will reset the system and can get the battery light off.

Hope this helps and thank you for using FixYa! Have a good one!

Is it one click or multiple clicks. If it's multiple clicks, it sounds like a dead battery. Voltage isn't always an indicator of a good battery, you need to have enough cranking amps to be able to start an engine also. If you have dash lights and it only clicks once, you could have a bad starter. An easy way to check this is to try and jump start the vehicle. If it starts up with a jump start, you need a new battery. If it still doesn't start up and it just clicks, you probably need a new starter.

Good Luck!

Check your fuel pressure at the regulator. If it isn't up to pressure you go no where.

the smoke is from engine oil, it is caused by leaking valve seals , after the engine is shut down for the day oil is leaking past the valve seals and getting into the cylinders then when you start up the engine the oil is burned off, this is a common problem, and there is a couple of things you can do to help the problem with out taking the engine apart and replacing the seals, try this first at your next oil change add some Restore to the engine oil it will soften the seals and give them a little more life, if this does not cure the problem after a few 100 miles then you will need to have the seals replaced, and this is a costly repair, but you could just live with the smoke it wont hurt any thing just keep an eye on the oil

That sounds like either your valve seals/stems. What color is the smoke? Are you sure its not just steam? Does it disappear after a couple of seconds? Please reply

When you swapped the alternator, did you also changed the alternator rectifier? Looks like its either rectifier problem or problem with battery itself. Try using battery from another car and see if its charging. This will be the easiest troubleshoot for now. If still not charging then use a multimeter to check the output of alternator.

Thanks for choosing FixYa and welcome to the site. If you have a vehicle that will not crank or just clicks when you try to start it, there are a few different things you can check to get back on the road. First, if it is clicking, or just clicks a time or two, this usually means there is no power to the starter. You need to check your battery first. You need to test it and make sure the battery is good and able to hold a proper charge. You want to make sure your battery terminals and the battery post are cleaned very good. You can take a metal brush to the terminals and the battery post to clean them. Make sure the metal ends of the battery terminals are not cracked or damaged. They can prevent you from getting a good connection. You also want to inspect the wire that goes from the battery to the starter for damage. Once your at the starter, you want to make sure it is not caked with oil or other fluids.. If it is, it can prevent the starter from working. You want to make sure the starter is hooked up properly and the connection is not damaged or loose. Your starter may be bad. Try hitting the starter a few times. It may be enough to make it catch and start, just enough to get you home. Of course, it will need changed. If you ever work on the starter, make sure you unplug the battery before you do. It may be your starter solenoid that is the problem, so don't forget to check that as well. Now, if it is not clicking, you should check your ignition fuse first. If your inside lights are not working or your lights are flickering, this is a sign of a bad connection. Once again, you need to refer back to the battery. Many people don't know that if the battery is not giving off the full amount of power, chances are, the parts will not work correctly. Lastly, if the starter is not engaging the fly wheel, your car will not start as well. By learning what to check for when this happens, you can save time and money in the future. As always, thank you for reading and best wishes. Thanks for using FixYa.

Yes. your springs and shocks are worn outhat is why it sags in the rear.

Inspect the wiring. Make sure that the terminals are cleaned including the ground. Try to jump start it by connecting it to the battery of another car. If it runs, check your battery and your alternator as well if it is charging the battery correctly. If it does not, inspect the starter relay.

repair the drivers side door lock its only a plastic ring clip broke by the sound of it

I assume it didn't work before you changed the bulb either. You'll have to check for voltage at the bulb socket when the low beam headlights are turned on. If there is none you'll have to trace the wire back to where it splits from the right low beam headlight. If there is voltage there you have a problem with the new bulb.

Can not drain the converter, nor do you need to

Do not have it flushed
Flushing has caused all sorts of issues

If your having it changed,as in paying someone,
then they should know what is the correct fluid

Stop by or call a dealer and ask,so you know &
feel good about what to tell whom ever

There are two lines. One is a high pressure and one is a return line. They both run from the pump to the steering box.

have you checked both fuse boxes, there is one inside the car and one in the engine between your battery and overflow tank, I had some light problems and found that one of the bigger fuses in the engine compartment was melted so make sure you check both spots
