MALIBU FUEL GAUGE AND TEMP GAUGE INOPERATIVE

- This car came in for a non working fuel gauge complaint.
during testing , i realized that the temperature gauge also didn't work
and no a/c compressor operation
I apologize if video is a little rushed, but the customer was waiting in the show room for this one
Fantastic video, this worked for my 2000 Malibu. Fuel gage, temp gage, and cruise light were out, all because of the blown 37 AC BFC 10A fuse.
that's so funny....i just found a bad AC diode last week at work, and I hadn't even seen those little ones for AC before. Now I see your video the same week.
I was driving when I turned on my a/c and the fuel gauge and temperature gauge all stopped working . From your video I'm going to change some fuses and hope that fixes the problem. Good job with your diagnosis. Wish me luck...
So replace the AC Diode ?
Wow!!!!! Who would have guessed that those 2 gauges stopped working because of a compressor.. Nice work
Exactly. I had the same problem. It was the fuse 37.
This fuse will also blow when you short the battery on this car, the tell for me was the fact that the radio acted weird only in the ON POSITION not the ACC position (worked fine in ACC) and the CHECK ENGINE light flashed when i turned it to ACC and went out untill i turned it back to ON position, normally it would stay on continously since i pop 403/405 codes daily thanks for the wiring info, all the info was gone off my power distro lid and the car is 20 years old the manual is long gone
thanks for making videos im the head tech at my shop but i have no one to build skills with you guys
sucks when the costomer is waiting it seems like a unnecessarily complicated system great video
Great video James. It really saved me a lot of diagnostic time. Thanks!
+
It's nice to see you making videos again
Great vid. Jim She will be back as soon as it is warm!
Or turns on the defroster.
I have a 2003 Chevy Malibu and Ive replaced the Fuel Pump temp sensor and the Cluster and still no Gas gauge or temp gauge.HELP
I wasn't expecting the AC to be the problem! lol Nice job James. Thanks!
I have a 2001 chevy Malibu my gas n temp gauges is not working they told me to replace the fuse box under the hood do u think dat would work
This one is definitely coming back for the second part! I am interested on the issue of blowing the fuse when the door locks came in to play, I notice that even with the A/C on, it was holding but when the door locks were applied it blew. Maybe a bad Body control module or a door lock relay shorted?
I check the diagrams and BCM only supply power to control side of door locks relays, on the other side the power for A/C clutch does get supply from the BFC fuse 37, so interesting on see the fix.
Nice video good diagnosis
+Maic Salazar I think the doors cycled right after the fuse blew again since the bcm lost power
you just saved me a couple hundred -THANK YOU!!!!!
I like the term flywheel diode for those which I've seen used only once. Flyback diode is another term used that has been borrowed from the 60s TV repairman's manual and really leaves one wondering WTF iszat then. Leaving it out did nothing to help however, the AC clutch magnet coil has an intermittent short and while you had the diode out it just didn't feel like shorting. Soon as she gets down the road a couple of blocks it will be ready to blow the fuse again. Failure mode for all coils include the rare intermittent internal short. Interesting that they would power those two gauges with the same fuse, but it's now a tell for the issue thanks to you. As one can expect the free bbbindustries diagrams don't show the gauges on fuse 37. Worth exactly what you pay for. And the purpose of the flywheel diode is to prevent arcing across the relay points wearing them out prematurely. Craptastic double underated relay needs all the help it can get in the first place.
+Lee Barnes yea. I left the compressor unplugged so the fuse wouldn't blow. She will probably call when it's summer and too hot
Thanks for the follow up info, I take you already knew then. So she got the best that could be done at the moment and on a budget = good job James.
alotta research for a blown fuse😄
Thank you so much that happened exactly the same thing to my car I had no idea to check the AC fuse
Im still left with a fuel and temp. gauge problem. Im in texas and its 100 degrees out, Unplugging the ac is not an option for repair!
Mine needed a new ac compressor or at least the clutch coil to fix it
Thanks for this video! We had the exact same problem occur on a 2001 Malibu and, after watching this, I was able to find the bad fuse and fix the problem in 1 minute!
question, so the solution is to unplug the ac comoressor?
Awesome work! Love the videos
Not a mechanic, but I was curious if the heater resistor could be part of this issue with the fuse blowing when the a/c is pressed. I have an o3 malibu, no issues with a/c at all, cooled great and all. I installed a new passenger door lock switch and then next time I tried to drive it no gas or heat temp gauges working. I have the same issues as this video shows. Replaced 37 and also a 20amp for the lighter I believe, whatever that # was and turned on ac and it popped the 37 again but 20 was fine. I only have hi speed on my fan and has been that way for a while, I believe that is the heater resistor I need to replace to fix that. Just surprised the a/c could be bad when it had been working fine and no issues. thx.
+Tony Castillo that fuse goes to the ac relay and the bcm, which does control the door locks but just the switch input not the load side of the locks. It grounds relays for that.
the only thing I can think to rule out the bcm or wiring is an amp probe wired into the fuse socket and see what it draws without the ac turned on and then with ac on. Also pull that diode and see if it pops or not. The diode could be shorted
So what was the final fix?
Change the a/c clutch winding pack would be my guess and since the ac was where the short was anything drawing power from the bcm could foul from it
Thanks for the info
Keep them coming James.
I have 02 Malibu my gas and temp stopped two days ago I can't find issue Mechanic said fuse from wiring HELP ME PLEASE
I hate it when the emission police come around because you pretty much have to kiss their butt or you know that your life won't be worth living in the near future. Another diag well done, Jim.
Nice one James!
I'm having this issue. I live in florida it's summer and my air never really has worked the compressor comes on but never cools the car really. anyways so I don't allow my toddler in my car and it sucks. but for this and air do I need a whole new compressor or something?
+Faith Mullins mine, the compressor was shorted out . Blows the fuse and doesn't work after that. It needed the whole a/c compressor
James Danner uhhh I wish it was 100 degree weather., how much does something like that cost?
+Faith Mullins u were saying that the compressor comes on tho. My symptoms were the gauges didn't work and the ac compressor didn't work
James Danner oh cause in the video you could hear the compressor kick on and the door locks then the fuse blew.
+Faith Mullins yes because the issue I was chasing was the gauges that were not working.when I found that fuse blown, I put a new fuse in and the gauges worked again until I tried to turn the air conditioning on. Then the fuse popped again and the gauges quit working again. U said your compressor works.
Let's start over. Do you have the same gauge issue that I had?
Do you know if the compressor works?
Is it popping the fuse ?
Or does the compressor work and just the air is not cold?
an 03 with 44k on it. impressed.
nice video James
Same problem. Disconnect battery for a minute. Problem gone. Guess I got lucky.
typical gm gas gauge
Dude are your from delco? That ackcent hahaha
Record diagnosis
Nice
tldr; check fuse 37
Wtf show something I don't know
