My speedometer stop working on me
Ever since the dealer replaced my instrument cluster, the engine light will flash above 65 MPH if driven at a constant speed (random misfire). If I drive at various speed going from 60 to 70 back and forth, its fine. I took it to the dealer (another), and they can not find anything wrong with it. I had them replace the wire and plug, still no help. One old mechanic told me that when they replace the instrument cluster, they did not recalibrate the crankshaft. Could this be the problem? Been driving below 65 MPH for the last year. Can anyone help?

when I slow down to park in a parking stall and turn the steering wheel sharp to the left or right the engine shuts off, but will start right away.
I have a leak somewhere in the windshield washer system. However,I can find no liquid under the car, but over 1 gallon has leaked out somewhere. I hope it is NOT inside the car panels somewhere. Also,The rear window washer does not work either.I need a diagram of where the distribution hoses for the washer system are located.
I have a 2003 Chevy Suburban Z71 and it has been a great car. Because I drive my young children around in it, I have a concern that they are riding along in the rear seat "unprotected" because there are no 2nd row airbags, or side curtain airbags. One of the children is still in a booster seat with side protection and the other is ready to move out of one. The car was manufactured before Chevy included them as standard safety equipment. Also, there is no stabilitrak/ traction control on the vehicle. Would you opt for a new vehicle that is more up-to-date on it's safety features or do you think that the Suburban's size/ weight would compensate for this in a collision? Safety ratings for driver and passenger are 4/3 stars respectively for this model/ year. Thanks for your input and help in the matter!
The left blinker won't come on unless the brakes are pressed then it comes on solid not flashing. The fuse is not blown; I tried a new fuse just to test it. HELP!!!!
Should my A/C compressor be seizing every 16 - 24 months? It has seized every 2 years or less since we bought the vehicle in Nov. 2002. I understand that metal fragments get thrown through the system, causing the entire system (including rear air) to be cleaned out. do you know why this might be happening?
My ABS and Brake warning lights stay on all the time. Tried to replace the fuse and as soon as I put a new one in it blows. Any suggestions?
My drivers side wiper will not work. The passengers side does. It does move a little(about 1 inch)
I had this seal replaced about three years ago and it started leaking again last year. Had it replaced again at a chevy dealer again just over a year ago and they are now out of business. My brother is a mechanic and he replaced a few weeks ago and again its starting to leak. He said he tightened it up as much as could but doesnt want to damage bearing. Noticed that assembly had play before replaced and when complete everything was tight, a few weeks later leaking again and assembly has some play, we are going to take shaft out and try to tighten more if it allows without doing bearing damage. rear end shows know signs of scarring or damage that would allow fluid to leak out. Is it common to have to tighten down on these seals? do they take a few weeks to seat? we are very confused-any advise/help would be very appreciated. Thanks, Bill
