Very good timing and great job getting it fixed.

I've had AC problems for a year. Every time the car is stopped the AC would turn off... I couldn't find the fault, I almost changed the climatronic. Until I saw your video and one of the leaf fuses next to the one that burned on you was burned out. I change it and it works perfectly. Thank you so much!

Same here. I replaced my whole fuse box to be on the safe side. Mine was very melted

Thx Mucho! I had a dirty 30A fuse over the battery. Cleaned out the fuse contacts and bam, AC. I had changed out the compressor a few years ago. I'm going to share a fix w/ you. During my compressor swap, a mouse at the wire on my ATS (Atmospheric Temp Sensor). The FCU thought it was 32F. AC would not turn on. I discovered it after I went thru the Shop manual electrical section and jumpered out the ATS at the FCU to discover the problem. Note, the ATS was never mentioned in the Shop Manual..

Hi man thanks You won't believe that I spend 450€ and change everything and nothing didn't work .. Until I saw you video man Hey thanks again

Cheers man from a fellow youtube mechanic. Had the same problem, fixed in 2 mins with the ten amp fuse

Absolute lifesaver with this video!

Had the same issue right now. Car was in the workshop for 2 weeks but they couldn't find the problem. They tried things like changing fan control module and AC control module ( i have climatronic), some new sensors etc. but they haven't noticed this little oxidation on this fuse. to be specific this fuse is for level1 of the coolant fans. level2 is one of the bigger fuses. by turning on AC they blow both in level 1 and this engages the AC. with a bad fuse the fans won't spin, the signal to the control module is missing and because of that the AC won't work.

Mine stopped working and both fuse 16 and the one one the battery is ok. But....when I remove fuse 16 the fans starts and when I put it back they stops. Ground issue? The ac worked fine before I parked the car for the winter (in a barn)

Sounds strange. Barns have mice and rats, which I hate. Hopefully they haven't chewed through any of your wiring. Many people have had an issue with the large alternator cable, as Gordoman says, about 3 years ago in the comments below.

Well lol I been bragging on this pos car a great ac and then no ac . I have no clue on how this system works . So after a few ubtube I changed the ac module and no change . I could jumper the fans and ac compressor and make them work . I even tested the fuses with a test light but it was not under a load . As Paul Danner said test under a load . So when I tried to pull the fuse which would light up the test light it was stuck with the green crustys . Damn lol cleaned up the blades and sprayed them with wd40 . Work good now thanks for the information.

Take the fuse box apart note where those in line fuses go they are all different amp as I didn’t oops to clean the connection properly great video though

Check the fan controller module. It controls the fan and ac

Same exact thing happened to me. As a matter of fact VW Beetle owners had a class action suit against VW years ago. I have replaced my top-of-battery fuse block once, and I replaced the alternator to battery cable with heavier gage. That was about 10 years ago, and no problems since. I think the cable has been the biggest culprit. My original was absolutely fried. Horrible, incompetent design.

I haven't had this issue since I replaced my fuse, but quite a few people have said that the alternator cable will need to be replaced if you're experiencing this still. If you look further down in the comments, this is what Gordoman mentioned.

I have an 03 jetta and the cooling fan wont come on no matter what, fuses and voltage on top of battery are good but every time i put a new fuse into fuse #16 it blows when i turn the ac on. Any help would be greatly appreciated its too hot to not have ac
