replaced switch checked fuse still no light.

i just bought, a 1997 ford mustang (5 speed) from a dealer, only had it 3 days now. anyway, my 2nd day riding around in it i started to hear a buzzing in 2nd gear, it's become loader and is now doing it in 1st,3rd, and 5th. i'm really worried as i feel this may cause major damage to the car itself. I didn't hear the sounds when test driving, they even said they had placed the transmisson, and cluch. HELP

then heater blow warm air then the air turns cold then it warms up again.

After locking the doors w/remote to set alarm with in 30 sec to a min the alarm goes off

I took my mustang into a local shop with the agreement of $1200 total for a motor swap and installation. Two months later the guy tells me he's got it running, which is good, but its now gonna cost $2000 due to a fuel pump and ECU. I know the ECU for my car is $230($150 after core). And a fuel pump is $100 give or take five or ten dollars. Which makes my total $1530.
1. Did it even need these to things to begin with?
2. How much should the installtion charge be for each of these?

My check engine light has been on for a couple of months now but car runs OK, however, lately I have noticed that the temperature guage goes up to about the half way point when I am sitting in traffic & not moving. What does this mean?

front brakes and rotors and calipers.

starter stays engauged on flywheel for 1 second after starting car

is there a fuse that operates button for gas door or do i replace the switch if thats the problem


replaced the light bulbs and fuse but brake lights are still not working...what else could I do to check before having to take into a shop. Low on funds and need to repair myself.

I had recently had my car repaired for a blown coolant hose. After, my car was working better than ever. However, about 2 months ago, I stopped getting cool air. The heat (as far as I can tell with the summer temperature as it is) still worked and works now though. A few weeks ago, however, none of my AC settings would work and the only air I could get was through the front window defrost. That is to say, when i turn the knob, all of the settings only direct air to the front defrost.

What could be the problem(s) and how much does this look like it will be to repair?

power seat on drivers side has stop working with the seat all the way forward.when i bump the switch i can feel the motor on. what do i need to do to fix seat?

my drivers side window and drivers side door speaker do not work.i took out the door wiring harness and found one wire broke ,so now my passenger window works fine.but my drivers side will not work and the speaker will not work.do the wires go under the dash or back to the rear of the car .not sure where to look next.there are so many wires.or could it be the master switch?

I have no air coming out of my vents.my air condition gets cold,my heat gets hot and only blows out the air through the window defroster.any ideals what controls the airflow ? from defrost to or from the vents ?
