So the time has come...my first car is about to be sold.....
1998 Volvo S70, it has been a great 3 years.
Anyway...I have a buyer for my car (my cousin) and he's aware of all the problems I've encountered. Any of you have any idea if its possible to diagnose some of these just by myself. Just want to see if any of it is possible.

ABS Light
Service Light
Right rear window doesn't go up from drivers side (have to use the other switch)
Faded Paint in some areas.. (Touch up paint any good?)
Coolant used to leak in the passenger side carpet. It's the heater core, I use stop leak every year or so and run the heater full blast to cover it up.)
Central Locking System acts up when under intense heat. Turning the key twice to open all doors (only opens one or two) button on driver and passenger only opens the door its on.
Blinker relay goes out under intense heat too. Doesn't flash anymore.
Weak A/C....

 

Let your cousin worry about that stuff. Give him this web address after he pays for the car.

 

Sounds like you have (errr, had) a pretty typical S70. Bet your radio lights are burned out too!

 

Yep haha!! Any estimate on what it costs to fix all of this? Just curious...

 

Everything you mentioned (with possible exception of locks issue and paint) are normal maintenance items on cars like this; if you DIY you're talking a few hundred bucks or so in parts.

BTW is the car due for a timing belt too?

 

I just did radio lights in our S70, pretty easy. You can read the DIY in the 850 section.

 

Yeah. Previous owner had one at 74k. Car is currently at 130k
