check the existing wiring see where it goes through the firewall from boot to back seat . use a coat hanger wire or a long thick cable tie to guide antenna cable through . Tape cable to guide and then gently pull it through.

run the fault codes indicates a cat converter problem coupled with injector problems

dim lights are generally bad ground / rusty -loose ground points or wires

Hi Steve, you're so close to the answer already. The feed wire is broken and sometimes it touches and sometimes not. It might just be the fitting on the end if you're lucky. I'd replace the whole wire just to be sure ;)

If these are the gas tube style supports, there is a metal half moon clip on either end that has to be pryed back to release and removed to pull the tube off the most that it connects to.

make sure that you have the right item as relays are plug in from the top of the panel

Hi,sometimes this can be becouse the filter and transmition fluid need changed,people tend to ignore this area but its just as importent as changing the engine oil and filter,also there is a additive you can use that helps to make things run better inside the transmition its cald,(xado)you can find this on ebay,I drive a mercedes and always use this product it dose work. I hope this was some help,and just to say I dont sell or make any money from these people who sell xado I just know that it works,all the best.

Check the speakers connection and that should give you at least 8 of the colors. The ones left then are going to be ground and power and display power. You can figure those out with a meter.

check the fuse .and all of the bulbs are working.if ok then change the brake switch.

The speeds are controlled by a resistor pack. Changing the resistor pack may restore full functionality. Volvo heater fans are notorious for squealing. Usually they are run at a speed that doesn't squeal. If it squeals at one speed, sometimes a different speed won't squeal. The resistors seem to eventually fail. They are fairly cheap to replace.

It's under the the hood not inside the car as usual

Under the hood passenger side can't miss it

Check fuel pump I usually tap on it

Either in the footwell under by the pedals or the passenger side under tby the door.

Did you change the fuel filter to?

I would try the brake button under the pedal it tells the computer you are depressing the pedal and unlocks the shifter or there should be a manual pull switch. It works like a hood pull you pull up on it and switch the car out of park. It should be described in the owners manual. I have a few more ideas as to what could be causing this issue but lets start with these. Hope this works.

the lights relay is located below the radio, you can get to the relay by removing the ash tray. the relay is red and round and is on the same panel as the fuses. Good luck

possibly: timing or fuel delivery?????

remove both leads to your battery .if you have a clamp over the battery screw out the rod holding the battery.

check the sensor on your back aisle clean and check the wiring.
