2005 Mercedes-Benz ML500 Questions

A/C is blowing, but not cold. I checked freon already and its fine. What else can be the problem? Thx

First time problem.

The horn blowing problem developed after having the vehicle serviced and new brakes installed. It was returned to the dealer to diagnose this and a problem with the brake wear light and coolant light illuminating and they replaced a faulty brake sensor & tested the coolant system for leaks finding nothing. We were told they took apart the horn assembly but after picking up the vehicle and driving less than 1/4 mile & coming to a stop, the horn blew and then did it again during a right turn. So far the brake and coolant lights are still off, we're keeping our fingers crossed on both these issues but frustrated with the horn because it could cause problems in traffic or distract other drivers. FYI the vehicle has been at a MB dealer 2 weeks out of the past 3 weeks to address these problems.

if its cold starter stays ingaged till switch is turned off and wont start..once it does start it stalls continuesly...it pulled code for crankshift position senser..I changed it..but problem is getting worse and still pulls code for cps senser..could it be a bad senser from new..problem started 5 months ago..once and a while after 5 min drive time same spot on road it would die..after couple tries it would restart ..after time became more frequent..now starter stays ingaged when first attempt to start 4to 5 times..once it starts it runs like crap..stalling and starting and stalling..it does pull up crankshaft position senser..could it be wiring issue..don't wanna keep changing that senser....

the rear left..driver side turn signal will not work...what can the problem possibly be?

leaking power steering rack, technician ask to change the rack & pinion. what is the cost on that.

Why when I put the car on Drive, it stays not only in Neutraul for about 10 seconds then switch to drive. what is the cause?

It started after a collision that damaged my rear bumper, I'm wondering if this could have something to do with it. I'm auto-illiterate so any ideas would be greatly appreciated! Thanks!

Problem started Dec. 20, 2012.
already replaced power steering pump.

the filter is about 10" x 10", my guess is thats its under the glove box.

It don't always happen but when I does it putters before it accellerate. The Ai Mass Flow filter has been changed 2X's. I'm starting to think its a fuel problem but unsure

Dash board shows high oil blinking after oil change.

There is a whole in the pipe which allows the SL500 to rise or lower. Please tell me what I have to do and the name part to be replace.

When I am refuellig the ml500 the gas is coming back at me as if there is air in the gas tank pushing the gas back out at me. I tried pumping the gas slowly and the result is the same.

while driving on the freeway the engine just cut off pull over to park try to restart the car.it want to start but dont want to turn over
