VIDEO: GGC – 40 – No Dashboard Heat: Troubleshooting Electrical Problems


It may be an abnormally warm winter so far, but when we discovered that our dashboard heater was no longer blowing, it quickly became a priority. In this video, Derrick troubleshoots the problem, and eventually makes the necessary repair.

  1. Another atta boy from here. Good technique and systematic elimination. Don't know if it's due to a hidden problem like motor windings being corroded and shorting out some windings lowering the resistance of the motor and thereby drawing more current. You might check your manual if you have one like Chilton's or Hayes and see if they tell you the proper DC resistance of the motors. Take care

  2. fusible link?ย  Lets make a wire that is actually a fuse, and hide it somewhere unknown.ย  and oh by the way, put fuses downstream to make you think its notย a fused situation.ย  am failing to understand the design intelligence that created fusible links.ย ย  Supose its because in a crashย wires are going to short, and cause fires, and you best just have them disconnect, instead of starting fires in the engine compartment.

  3. Interesting, informative and scary all at the same time. For me it would have cost a fortune to have this problem diagnosed and repaired. I can only imagine what a Mercedes dealer would charge for something like this. Hopefully not something I would have to deal with for many years to come. ๐Ÿ™‚ Wish you bother a Merry Christmas.

  4. Ah yes! The "lovely" "fuseable link". Somehow I had my suspicions, and that's only because I had to have my old van towed to my local garage, (many years ago) because I blew one, and couldn't for the life of me find that darned thing. Turns out it was a BIG fuseable link. After that, I kept a spare on hand.

  5. I should not have enjoyed that, as I generally am bored to tears with auto repair stuff, but you make things so interesting-I actually had a little fantasy about being auto-handy and fixing something on my car after watching this. Great stuff, as ususal!

  6. You could have just purchased an in line fuse holder and put a fuse in that line in place of the fuse link wire. That would have made it a replaceable fuse if future problems arise, a glass fuse with a slow blow fuse in it. And I agree, remove the tape you put over the fuse link wires. Accumulated heat within the link section could cause failure of the links for other circuits also.

  7. That's why I hate electrical malfunctions!! So much costly labor goes in (for me) to diagnose the problem – and then a few pennies worth of wire to fix it…
    I salute your sleuthing skills – that was remarkable. You certainly saved yourselves a bundle!

  8. I really love how much information you give in your videos! It's super educational, especially for someone like me whose looking into van living and has basically no car knowledge.
    Thank you!! ๐Ÿ™‚
