Answer to "2009 ranger heater runs cold"Does it heat up after the engine is warm or is it cold no matter what? If it heats up eventually, then that would be your engine thermestate, replace that and you will be good go. If it does not heat up at all, 1) check your coolant level 2) Do you smell antifreeze in the cab of the truck? 2a) If you do that mean you have a coolant leak in your heater coil. It is the coil that connects to the engines cooling system that distributes heat to the internals of the cab. 3) If fluid is good, when is the last time you flushed your coolant system? 4) If you are flushing your coolant system, change out the heater coil and check and make sure all the valves are in working order 5) I would buy the repair manual from a local autoparts store and follow their procedures, that way your not wasting time guessing :) Happy Fixxing.
Answer to "Vertical line after LCD Repair."There are two possibilities: 1) The screen is warped, (Manufacture defect) (1) Would explain why when you press down on parts of it the lines go away. Your re-aligning the internals to make a solid connection. 2) Faulty Digitizer, (Manufacture defect) (1) Same as the first reason, but it is generally caused by the hardware IO’s chip giving a crappy signal. Firm bet is on number 1 though. Call the manufacture and see if they still have it under warranty, if it is not, you can replace the screen cheap.
