Alright so i have SOME problems..
not really CONCERNING but i would like some help fixing them

1) backglass heater lines not work

so ill start with my back glass the last one i had SHATTERED via.. natural causes? or just that its 18 year old glass but anyways took it to a RELIABLE (not so much now) glass shop and they REPLACED it with USED glass
so i was told they checked the lines and there shouldnt be any problems
so i was ready to fire them lines up and see how they fly
pressed once.. spots SPOTS.. of defrostation... WHAT TEH frick
i paid them 300 and 190 for SPOTS

QUESTION: well is there something wrong with the lines?

cause im really mad cause they didnt do a good job cleaning the glass up and really drove my volvo hard..

going to take it in today (wednesday) report back

2) TAIL LIGHT - (rear left side tail light bottom LEFT corner box)

ok.. so before problem #1 happened i was undercover from rain and wind
to change my tail light which blew.. normally which was fine. so i was going to replace it and i see a bunch of water.. basically 1/5 full of water so like an idiot i just tried to replace the bulb and go but it doesnt seem to work.. so it must be the water and so the question i pose is:

QUESTION: HOW DO I GET RID OF THE WATER from the lens box?

note: i heard i could drill a hole into it? will that work and will it break?

3) Noise - (sway bar bushings?)

The noise being a harsh RUBBER SQUEEZING sound like ur bouncing on a rubber balloon

well this has been an ONGOING problem i recently changed my sway bar bushings with scan tech bushings from FCP and.. i think they failed me.. my friend mechanic took off the sway bar.. and the noise stopped so my question is.. since ive been told it could be my Trailing Arm Bushings

what is the problem? ive been told to change my bushings control arm and so forth but its too expensive for me to do those repairs right now
i think i need to get better sway bar bushings..
what do u guys think?
the scan tech ones on this page

4) Seats ...

hard 2 find volvo 240 seats at the wreckers.. n pick n pull
what do u think i should do?
the seats i have right now are gone like they been yanked inwards towards the middle by big big guys or.. some other catatrophe.. and the bottom foam is losing its relisency so.. re upholster this stuff?

IDEAS?

THANKS SO MUCH for any support..
i really want to get these things fixed IF NECESSARY.. i love my volvo when it runs. :)

PLEASE ANSWER in a 1),2),3),4) style thanks
