Labor time and cost for rear suspension conversion?

I have checked all fuses, and read everything I could about it and have figured nothing out. All speakers are hooked up as far as I can tell.

it sounds like its rubbing. I have a 2006 buick rainier awd

When I step on the gas, there is a high pitched sound that comes out of the speaker. Sometimes it is a loud buzzing noise and if I turn off the radio then it is quieter. It doesn't happen all the time.

you can hear very low but can't turn it at full volume it is not any louder then all the way down.

My AC won't work in the front. The rear will work, front will if you are driving on the highway. The blower motor has been replaced still won't blow out the front unless moving. What do I do now? Rear air suspension goes down especially on the drivers side (when cold, rainy or sitting) sometimes it will stay up and others it won't air back up. Usually have to sit and let it run before driving so that it will air up. If there is weight in the back it tends to not air up or if it does it takes a while longer. How do I fix this?

I just had transmission fix was input gear . So I'm sure battery was unplug , what could have happened

when temp outside dips below 80 degrees cold air returns

none of the parking lights work on my vehicle. I have tried replacing the relay underneath the rear seat. that did not solve the problem I cannot find a fuse anywhere in the manual for lights work fineheadlights and tail lights work fine but all parking lights, and the side light when turn signal is on are not operating any suggestions?

Started out by not working all the time. Now it will not work at all and the heater control and radio feels hot. The vents above the radio have not worked since we bought the vehicle. It is getting cold and would be nice to have the heater working again. I looked through the owners manual but could not find anything useful.

This doesn't happen every day but getting to be more frequent what could it be

My rear liftgate won't lock or even latch. When I use the keyfob, it makes a noise but does not lock.

How do you remove the steering wheel? How to I get to the shroud to remove a retaining screws. I want to replace all four connectors.

This is the 2nd battery i have replaced in 12 months. Something is drawing power when the car is off. Now when I drive the blower seems to cut out for a split second and the enging rpms reveve up. I have auto suspension which is flat in the morning and is always pumping up when I stop at the intersections as well. My mechanic tested car and says nothing was drawing power as long as it was being tested. I have 109000 kilometres, gas mileage is showing 5.8 per litre right now
