A BIG Thanks to this wright up, and I saved a lot of time an money by replacing that thermal fuse. $4.75 for two fuses shipped to my house. About 30 minutes of bench time and then another 10 minutes to install it back in and....... Bada Bing... I got AC back. Great timing since they are calling for the first 100 deg. here in Texas.
You saved my day. I never thought that I would be visiting this post and get help so quickly. I tried all other avenues, but none so convincing in right answer. My AC started working after I did the jump on the fuse. Now I removed the jumper and AC continue to work. I will order the fuse in the mean time. Thank You! Thank You! and Thank You!!!!!
Front AC in 03 MDX stopped working. Will turn on then shut off after about 3 seconds. Fixed my thermal fuse as shown, but when I hooked it back up the fuse was blown again. What would cause this fuse to blow?
Thank you sidewinder, that was exactly the problem with my 2003 Acura MDX. I have the motor running with the jumper wire right now and I will order a new thermal fuse as soon as I am done writing this. The problem with my MDX was was when I would turn the AC on, it would turn the fan for around a second and stop. This gave me the clue that it probably was not the fan itself. Googling up the problem, your solution came up and this was it!!!! I was planning to take my car to a machinist tomorrow which could have cost hundreds just to diagnose the problem. Thank you again. It feels so great to exactly find the problem.
