The 4x4 light says its on but it is not working.

Almost everytime I use my Left turn signal, my hazard lights come on on the instrument cluster as well as the outside lights. I thought I might need to replace an outside bulb but all of the signals are working properly. The hazard lights switch is located on top of the steering column & the multi function turn signal/wiper lever is nearby. I wonder if there is a loose wire slipping that is causing this or if there is a part that needs to be replaced. Thank you for your help.

engine at no particular time will not start even turn over at times.receiving electrical power normally. replaced starting relay under hood and it worked. progressively getting worse and constantly replacing relays

2001 Silverado with 191,000 miles. New H2O pump, hoses Thermostat. This truck used to have burn your face off heat. I changed the heater door control motor a couple of years ago because it used to get stuck in the open position causing us to pull over and reset the heater control(by turning off the ign. and restarting the truck) or drive with the windows down. The truck now sits outside when it's not used.

I have a 03 Silverado I got a fabtech susp. lift and like a 2 inch body running 37"13x50x20R toyo mud terrains. The trucks is an ext. cab 4dr LS im having front end problems the driver side front tire is wearing some on the inside and it also dont drive as smooth as it did. I bought a list of parts pitman & idler arm, idler arm bracket, tie rods & all tie rod ends, upper & lower ball joints (both sides) hubs (both). I haven't put all the parts on yet because some ppl tell me some of the parts dont need changed. Idk I just really want it driving smooth and DEFINITELY not to wear on the tires have any suggestions????

i am wondering if it needs to be plugged in or something sense it is a diesel??

When the vehicle sits for several hours, the engine will crank normally, but won't start unless I press the accelerator to the floor and hold it. My mechanic diagnosed a bad fuel pump, but a new one didn't solve the problem. The check engine light does not come on. No codes either. Any ideas?

I replaced the switch, did not work, all fuses are good, I notice the lights flash on anitial start up of the vehicle, no codes came up on the scanner, what do you recommend?

I have been having problems with the "service 4wd" for the last 2 years, after cleaning connectors , I thought the problem may be over, every once and a while the service lite comes on, I reset it , test it , everything changes (lites), I hear it change to low 4wd, but today, it snowed , I changed it to 4wd auto, 4wd, and the lights came on, and then I realized that the front wheels did not respond and drive. I was slipping as it was in 2wd. Any suggestions ? Don

Replaced upper and lower balljoints, Pitman and idler arms. Plus replaced the left wheel bearing.After all this, there is still loose steering.What did i miss? What else could be the cause? 4x4 with 5.3 liter engine. .Thanks.

Went to start it this morning and nothing, not even a click. All dash lights, interior, and headlamps come on as normal. Any ideas? It was working normal last night. Had a fuse block problem from new but that was replaced.

It was raining n I notice out of nowhere my 4wheel drive lite came on I never use it what does that mean n can I still drive my truck with it like that

Only 33,000 miles on 4x4 truck. Nothing shows on the code machine, and it happens after driving a further distance, and if the signal light is used or the brakes are used. Everything turning off and on by itself. The radio becomes statichy and sounds like the station is changing. The temp gauge looks all distorted. What is the problem and how much will the repair be?

i installed a cold air intake on my 2007 silverado new body style 1500. check engine light is on and have diagnostic codes. system too lean. the filter is huge. If i installed a smaller filter (less airflow), would that solve the system being too lean issue? would make sense to me...big filter=lots of air, smaller filter=less air. just curious

I noticed my coolant is significantly low with not a drop on the ground where I park my vehicle. My oil change last week(100 miles ago) required the technician to move sludge and debris from the drain hole with a screw driver to allow oil out. The heads on my truck were tested and I would presume cleaned. I bought this truck at 70k miles it currently has 75k on it, and am wondering if this is due to lack of maintenance prior to me or if the head gasket replacement job hasn't rectified the situation.

checked oil filter and plug looks like oil pan seal how hard to replace

I try to put it in 2 hi but it will iick outbof gear and does the same thing in 4 dash said service transfercase once but no codes.Is it supposed to run in the 4 wheel automatic mode? If not what would be the problem?

into 4 wheel drive, what do I check next? I have checked the fuse.

Message saying engine power reduced

the transfer case control module makes a clicking noise in the dash and 4whl light is on

when I come to a stop the rear right side rear end has a thud sound to it when I stop or let off the brake. it does'nt do it every time.

I was getting all 3 codes p0172,p0175,p0449. I put on a new vent valve solenoid and that fixed the p0449 code. I'm still getting codes p0172,p0175 and as it gets colder outside it is getting harder to start in the morning or after it has cooled off completly. But starts fine after its started once. Really cant afford to put in the shop right now so any help would be appreciated.

I have nothing covering the sensor by the windshield and it doesn't do it all the time and it only does it at night. I check the alternator and battery and are all good. Could it be the headlight switch or the turn signal switch

With scanner can turn on and off air pump. Found both check valves plugged replaced but still will not run monitor can watch pid data both o2 sensors drop. replaced both front o2 sensors just in case they were lazy. What else is need to run monitor?


window will not go up or down

My battery died so I checked my charging system and found out that my alternator died as well. new battery and new alternator but my battery light on my dash is still on. charging system is working. Cant figure out why the battery light is still on. any clues as too why?

is the fuel tank preasure sensor actually inside the gas tank or is it on the top of the outside of the tank.

I getting the code p0449 and going to try and see if a new evap. sensor relay will fix it but I'm not sure where it is I'm thinking it's by the gas tank. I'ts a 09 silverado ext. cab with a 5.3 Any help would be helpful. Thank you

previous noise in heater location, fan works fine on first 4 levels.
