Chevrolet - Trailblazer :: 2003 - Intermittent Oil Pressure Gauge Operation
Feb 14, 2015
2003 Trailblazer 4.2... Two times now, like every other start oil pressure gauge is 0. The engine runs fine, oil level is fine, thinking of replacing pressure switch, ie sending unit after checking connections of course
. Was curious this is a simulated pressure gauge as I read on some other posts?
Supposedly the gauge unlike the stepper motor I need to replace for the speedometer is actually voltage controlled by a circuit board in the cluster.

I'm trying to figure out what could be the reason why I have Intermittent wiper operation on this truck. It's a 99 Chevy 1500 4.8 4X4. It's almost like the wipers have a mind of their own. Sometimes working properly but most often not operating when needed the most. Is this one of the set-ups that has a pc board with a bad/cold solder connection? I'm sure that one of the regulars here has come across this at some time or another and found it to be a simple fix.

The ac condenser unit will click every 7 seconds followed by a 3 to 400 rpm surge for 5 seconds or so, drop rpm then repeat. Belt looks fine, no slipping, new plugs a month ago, newish air and gas filter, does it in neutral or drive, read many ideas from low or high freon, iac, throttle body cleaning, o2 sensor? no codes thrown. Maybe coincidental but was discussing o2 upstream sensor recently on this board. The car experiences the same symptoms while driving.

'97 F150 4.6L 4wd automatic... My gauge jumps around, sometimes it works and other times it shows no pressure. Could that be the oil pump? Or is the gauge most likely bad? Whats the actual purpose of an oil sending unit?

The wipers on my '99 SW1 are becoming intermittent in operation. The intermittent speeds change, the set speeds work, but all operations are not stopping when turned off. They do turn off when I turn the ignition off. I think it is the multiswtch on the steering column, but haven't done much troubleshooting yet.

Speedometer in 2003 Trailblazer is showing wrong speed intermittently. Seems to be a known problem to GM. Is this something I can fix myself?

We have a 2005 Chevy Tahoe. Been running great. Has 140,000 miles on it 80% open road. Couple of weeks ago was highway driving and noticed the coolant temp gauge went all the way down to nothing, and then back up to normal (middle of the dial) This happened 5-6 times and each time as the temp rose back to normal, the transmission would lurch.
I took it to a mechanic who could not figure out what was wrong, but acknowledged it was running terribly. He said that was what he would try before going to a dealer. I agreed and the car instantly seemed to be running perfectly. Now a couple of weeks later, the coolant temp gauge is dropping again. It is not going all the way to nothing, and the transmission is not lurching. It goes down from half to a quarter and then back again. So something still seems to be wrong. Otherwise all seems to be well.

I just bought a used 2011 Santa Fe. Two weeks ago, the right window stopped working. Neither the left or right switch had any effect. All other windows worked. A few minutes later it was ok and has been since. Today the left window did the same thing; was inop for a while then ok.

I have a 2001 Chevy S10 4.3L. The CHECK GAUGES light stays on, and the oil pressure gauge stays at 0. The oil is full, and the engine runs and sounds fine. I drove it about 5 miles with no change. Up until now, the gauge has worked normally. Could it be the sending unit?

2000 Blazer LS 4X4. 186k miles. It would seem that my heater control will only work for defrost and face-vent operation. (Just happened yesterday) When I move the controller from the off position to defrost, I can hear the system moving the flaps into position. But it no longer moves for defrost/floor or just floor control. Would changing the heater control solve this problem, or could it be a bad vacuum line?

I have a 2006 Chevy Colorado, 5 cylinder, automatic, 4wheel drive with 62,700mi. 1st problem occurred in 2013 new thermostat was replaced then in 2015 temp. gauge shows overheating problem again. All diagnostic problems have been analyzed by mechanic and nothing further could be done. Mechanic suggests to take truck to dealer. The temp. reading still shows above normal operation and the engine compartment has signs of overheating also. If the truck driven on uphill range the temp. goes higher I refuse to drive in this condition which will surely ruin the entire engine.

The daughter calls and says her '06 Trailbazers oil gauge goes to zero and then the oil warning light comes on. The gauge then comes back up in pressure and the oil warning light goes out. No engine noise according to her. Oil changed a month ago.
This happened several times yesterday on her trip to town but then started working normally and didn't act up again. This sounds kinda like a sending unit issue except for the intermittent part. Maybe the wire to the sending unit?

I changed the sending unit and replace the oil filter with a motorcraft unit and still can't get the oil gauge to read pressure. Since it is a gear oil pump I don't believe it is the pump.

I have an 01 F150 Lariat Supercrew 4x4 with the 5.4 Triton. The truck has 222,000 miles on it. Recently, I have noticed that when I am stopped at a stop light/stop sign while in gear, the oil pressure gauge drops to zero and the light comes on. As soon as I let off the brake and give it gas, it pops back up to normal. While driving, the needle never moves and stays consistent until I stop again, and back down to zero it goes.
If I put the truck in Park, the pressure goes back to normal. Same with neutral. It seems it is hit or miss and does not do this all the time, but I just wanted to see what your thoughts are. After doing some research I am leaning towards an oil pressure sensor/sending unit.... The truck runs perfectly fine, I just want to make sure it is not something more serious.

I have a 2003 Impala 3.4 with an intermittent starting issue. It starts perfectly every morning but after it is hot and I park it over 15 minutes or so it will sometimes not start. All the regular dash lights come on as normal but when the key is turned it does not even try to turn over, it is just silence, To get it started I have to hit the column shift lever upward several times and then it will kick right off with no hesitation. Sometimes I have to turn the key 10-20 times to get it started also. I had the battery, starter and alternator tested under load and they are all fine. It is not the security problem either that many impalas have. The only code I have is a PO 336 for crankshaft position sensors. Is there some kind of linkage in the column that could be worn that could cause this?
