The 4x4 and the blower motor both go out at the same time and then they will both work at the same time on my chevy 1500 silverado what could cause this and how are they tied together
Check your fuse box for a bad connection or loose fuse. if all fuses are tightly in fuse box I would suspect a wire on back side of fuse box having a loose connection if this was helpful please leave me a good review

If it is a ATC automatic control temperature , you will have to find the code. if it is vacuum controlled you will have to check the vacuum hoses that control the mode door. maybe something fell into the defrost vents and it got stuck. the only solution for that is to try fishing out the object through the vents..

There are what they call mode door's these days they have a electrical motor that turnes the door to different posistions...sounds like yours is become broken. It would depend on your expertise in the ac & heating system area to replace the part. Sometimes easy and most of the times the dash has to be removed.

It's simple!...Open glove box door...youll see a plastic shell that is the glove box rear portion. You should find 4, 9/32nds or 7mm (same thing just SAE or Metric) screw heads. Undo four screws and with a flat blade screw driver, gently pry out on shell at either side to clear the door straps. Once clear, just work out of resting place, set aside. You will now see like 5 relays mounted on top of the air handler. Remove bracket that holds four of them + one that is mounted alone. Pull out of the way. Checking both inside and outside, remove all screws, bolts, nuts as it were, until it is obvious there are none left. Now, this is assuming this is where your problem lies! If you are simply having a blower problem, it might be the blower module mounted right beneath and just behind relays on top of air handling box. Just take your time so you dont break anything. Good luck...theroad......

before you drop tank again, check fuses & relay.then disconnect fuel line @ filter turn key to on position should hear fuel pump run and get gas stream out of line. if no flow from line new pump faulty be sure & remove negative battery cable first good luck.
