Antifreeze leak. Dont run the engine without checking the level

If you are getting power to the switch, make sure you are getting power to the motors when the switch is moved. If so, make sure the motors have a good ground. If not, check the fuse box. If you have power to the switch and the switch is sending power to the motor and the motor has a good ground. you have a bad motor. If you have power to the switch, but are not getting power to the motor, you have a bad switch. If you don't have power to the switch, you might have a bad fuse. If you don't have power to the fuse, you might need to check a wiring diagram to see what feed power to that circuit in the fuse box.

It's fuse #41 in the under hood fuse block,

Quit guessing and have ABS codes read. Symptoms would be indicative of a bad wheel sensor which often fail with hub/CV failures.

Swingit into a partstore for freehelp. They may hav some lube for it allso

https://www.clubarmada.com/threads/erratic-tachometer.17405/ This thread has several suggestions from a failing battery to bad grounds or BCM problems.

Starter probably going out. Try banging on it with a light hammer or screwdriver, then see if it will work. If it works now, it definitely needs replaced. If your security light goes out after a couple of seconds of turning the key to ON, the security system is working right and not a problem.

Any chance u got a manual to refer to since it looks something that happens not very often.. like get reference books from reliable-store.com .. I'm kinda sure that's all u need..

If the "dead" battery has a shorted cell, jumping doesnt always work.

Put the dead battery on a charger for an hour and see if it takes a charge. If it doesnt take a charge, replace.

If it were me, I'd pull the entire sending unit all in one piece from the junkyard and install it. Bet that would solve your problem. Sounds like something in the sending unit is bad or bent or something or not in tank properly which replacing the whole unit will solve.

Check all fuses first

If the blower motor intermittently stops in all the speed selections. The problem will likely be the blower motor. I would not run out and buy a new motor until you inspect related components and see if you can identify other problems before ordering. It's possible that the climate control panel has a fault or the speed resistor. I would start at the blower and go to the next suspected component. If at the time the blower stops. If you tap on the blower housing and it starts to operate, that is it. Inspect the plug at the speed resistor and the blower motor. If the plugs and pins are damaged from overheating. They must be replaced before completing repairs.

While the problem might be a leaky head gasket or the degassing system blocked, the cause is probably an almost blocked heater matrix...
