How to change rear passenger side freeze plug on a 99 grandprix with out pulling motor

is it the 4 cylinder motor are you sure its not the waterpump leaking out weap hole ? .It might be one of those sizes that they make the rubber expansion screw tight freeze plugs for if so you knock the old freeze plug out with a hammer and 3/8" extension bar try to flip one side in carefully that causes the other side of the freeze plug to swing out where you can get hold of it with something to yank it out . If its winter and looks like it is going to take hours leave freeze plug IN and you can see of feel the freeze plug " you may be able to drain the radiator first then sandpaper the hole in the freeze plug (where it leaks at) okay go to auto zoan buy a pack of J&B weld (12 hour epoxy) after cleaning the sanded area dry it with lacquer thinner or acetone (nail polish remover) to dry the antifreeze from surface dry mix the J&B weld in two halves (about 2 tablespoons ) on a plastic mix it good ! if its rel cold freezing or below heat it just before smearing it onto the hole (leak ) you may cut a small disc(cardboard) the size of the inside of freeze plug put the mixed J&B onto the disc and smash it down onto the hole area " if you do this right it should be 1/8" or more 3/16" at the hole spot (you sanded) wait for it to dry (harden)all night or a day after words you can refill the radiator with coolant and get it full then you should be good for anywhere from 3 months to 3 years depending on how well you applied the method and other factors (not mentioned ) hope this helps someone of course if you can uses a hammer and socket to drive the original type plug in then do that put some sealer on the hole as you pound it in there you have 3 choices

I have a 99 pontiac grand prix the DRL's work but

With the Key in the RUN position, check for battery voltage on the brown wire in connector 2 terminal H at the DRL module. Also check for battery voltage on the pink wire terminal C of the same connector. if you see battery voltage, then the IGN switch and the two fuses supplying power to the DRL are working fine. Next, check the brown wire in connector 1 terminal H at the DRL module for battery voltage

Will back seat come down

As far as I can tell, the only part that comes down is the little door in the middle of the backseat. Your key goes in there and unlocks it and you can put it up or down depending if you are hauling anything. it is available when you pull down the strap that gives you the cup holders and center console in the backseat.

Clicking noise when driving and turning to the right

It is possible the engine cradle bushings are shot and the cradle is moving laterally or twisting during turns causing something like a wheel to contact the body. An alignment shop can check that for you.
