Today the AC on my '04 CR-V stopped working. I left work and it ran for maybe 3 minutes, then just stopped. I was hot today, about 100F. The car has maybe 55,000 miles on it.
The AC light goes on, but the blower doesn't run, not even if you turn it up all the way. I went to try it again this evening. It still doesn't work, but when I turn the key on and turn on the AC the radiator fan goes on for a couple of seconds, but only once for every time I turn on the key. Also, when I have the engine on, and I turn on the AC I can hear the compressor go on.
I've read a post on this forum here, explaining how to check the relay and maybe replace the resistor.
I had the same problem with our Odyssey van maybe 2 years ago, and browsing around I came on a site I can't find now as well as a Youtube video (here), explaining how to replace the transistor module.
I took the module out as it explains how to in the video, and (according to the other site) I just replaced the Thermal Cutoff, which looks like a small diode. It is available at Digikey (here) for about 50 cents each.
The Odyssey unit is a finned metal thingy with a transistor and the thermal cutoff in it. For anyone that had done this, is the CR-V unit similar? Does it maybe use the same transistor and / or thermal cutoff?
