    The clicking was the starter solenoid because the battery is done & doesn't have enough amperage to turn it Don't ever use years or mileage for any vehicle issues except suspension

Battery-- you look in your owners manual for
battery Group (size) & Rating in CCA

The Battery & Alternator-- obviously need to be
tested at a repair shop-- unless you would like to
share your expertise with us here

You never asked a question You just asked if it was
whatever ?? What is ----a no turn or no start condition!!!

Testimonial: "Thanks Peter I imagine by now you can tell I'm mechanically challenged and just didn't want to call for the wrong service when my daughter mentioned the alternator! When I tried to start the car it just clicked which I think means the battery but the car only has 53k miles so I though it best to get another opinion from someone who was more mechanical!! Thanks so much for your response I appreciate your time !, "

SOURCE: replace antenna on 2003 mr2 spyder

my antenna just stopped working in my MR2 2003 Spider. The motor still runs but the antenna will not go up and down. It made a weird noise and I had to pull the top of the antenna up to stop the motor from sounding loud.

Should I replace this or can you disconnect it and push the antenna up and down?

SOURCE: 2003 MR2 will not idle

I had the same problem. My check engine light was on. Took it to the dealer and they checked the code. It was the throttle control motor failure. The good news is I got the wiring wet and that seem to be the problem. They reset the check engine light and it runs fine now. Bad news is if I had to get the motor replaced they said it would be about $1300.00 I hope things work out for you.

SOURCE: 2003 toyota mr2 spyder 5 speed transmission grinding noise

Here is what is going on. When you push in the clutch pedal you remove the connection between the engine and the transmission. At this time all the parts in the transmission stop rotating.Since the only parts in the transmission that can rotate without moving the car are the input parts we can safely assume that the noise can only be from there.This can be a transmission input bearing. Worn Synchro mechanism (allows the transmission to shift without grinding the gears)Low fluid in the tranny. Or a bad clutch component. Top off or change the fluid. If it still makes the noise you need to take it to a tranny shop.

SOURCE: MR2 after 2 mins of starting the smt light comes on.

it sounds like the clutch actuator is worn out.
The clutch actuator has 2 parts:
1. the clutch master cylinder
2. the clutch slave cylinder.

Try to replace the slave cylinder first, and if it is still not solving the problem, then try to replace the clutch master cylinder

Good Luck

you need take old alternator with you to auto parts stores they can match up your alternator give you the correct AMP TYPE, your alternator amps is stamped on the out side alternator housing, the auto parts store can look up right amp alternator for your vechicle.when you say dont matter yes it does if you get wrong type alternator, your battery wont have good charge causing alternator fail early and battery fail early.

Water in the storage area behind the seats in my 2003 MR2 Spyder. Has convertible. I believe the drains might be plugged but don't know where the drains to check!

There is a couple of plastic pieces you need to remove inside the storage bins. Two side pieces to be exact, just a couple of pins. Here is a link to more detailed instructions.

Mr2 transmission

use only OEM Toyota trans fluid. If there is one lesson I learned with my MR2, its that Toyotas own trans fluid is the best. Yes, its a few dollars more, use it anyway.

As for your top, there is a product called Amazing Roll off. Its for boat canvases and its simply the best thing i've ever used. try it, you wont be disappointed.
