Hi there,
Wondering if anyone had some ideas as to the problem or had experienced this before and knows how to fix it. Let me begin.
A while ago (1-2 years ago) I started loosing some speeds on the blower fan. For the last 6 months I've had only high speed. No problem, just changed the blower motor resistor yesterday, and all the speeds are back now (when the blower is working).
Something funny started about 2 weeks ago, I'd get in the truck and the fan would work, then I'd park, and get back in, the fan didn't work. In fact, on occasion the fan wouldn't work, but I left it turned on, and 20 minutes later as I drove the fan would just start. Even this morning, the fan worked during a trip, and then after stopping the truck for a while and restarting it, the fan continued. But right now, nope, it stopped again on its own and just won't start. There doesn't seem to be any consistency with weather conditions either.
Yesterday I was testing things out and found that when power went to the fan motor, it worked fine, but there wasn't always power going there. So, perhaps something in between. Just to note, I've also jiggled around the control panel with the fan switch and heater/ac controls, nothing seems to change there.
Could it be a relay? Are there more than one?
Any ideas?
