finally got my boxster today, what did i do???
 

ok got it off the truck, it needed gas ,so i got gas and went for a spin. after that i started to try and figure what all the switches do.

so now.

my windows only go up3/4 of the way. they went all the way up at first.

and i have a blinking red light on the temp gauge. (that wasn't there when i took the spin)

can someont tell me how to undo what i did.

Try the microswitch where the top latches for the window problem, press it in with your finger and then push up on the window and see if that works.

Windows... Make sure that the top is all the way closed and latched. Put the windows all the way down, then try up again.

Blinking light... Check the level of the coolant in the tank in the trunk. Do not add the wrong kind of coolant. if it just needs a little, distilled water is best.

Welcome to the forum :cheers:

There are a couple reasons the temp light flashes, do a search for info. Check the coolant level in the expansion tank, it is probably low. Look for steam condensation above the cap, could indicate a bad cap or bypass valve. What color is the expansion tank? If nice white good, but if it is yellow like old parchment then could be leaking, check trunk under the lining. Lastly look under the car for white coolant residue, especially the water pump. Good Luck.

You may need to reteach the car brain for the windows. Run the the windows down (one at a time) and hold the button when it is at the bottom of travel and hold it for 5 seconds. Then run it up to the top and hold it for 5 seconds. The windows are supposed to drop +/- 0.5" when you pull on a door handle. This drops the window enough to open the door without pulling on the seals. If your windows don't drop, with all four handles, you may have a micro switch problem and or regulator problems. The regulators are a known issue with these cars. I have replaced both of mine and I would recommend only using the factory replacements. Don't ask me how I know.

Blinking temp light could mean a cross threaded coolant cap. Also make sure it is the latest coolant cap ending in a '4'.

78F350 is right. There is a lot of education required and it is scattered all over. Very few books and manuals of use except Wayne Dempsey's ,Bentley and the FSM.
You probably need to find a good Indie and a used Durametric also. This is no Miata !
