Not tight on plug in.
The fuse did not do its job.
WHY!

Actually the fuse did do it's job. Current demand never got abnormal. The problem is that any resistance where there is substantial current pull, heat will be generated. Since our systems are low voltage, it doesn't take much resistance to generate heat. Connector corrosion and/or poor contact wiper tension will cause heat problems. I've seen this before on a friends Hyundai where the current pull for one of the brake light bulbs melted the bulb socket due to a poor connection.

There are reports on the Sol forum from at least two years ago about similar problems. One member experienced a significant cost when his entire connector and parts of the wire harness melted.

Sorry to learn that you have had this issue. Have you used any kind of electrical grease? When I run into connector issues I clean them and then use a good di-electric lube to help preclude reoccurance.

Location of Blower Motor

I think I'm having this same problem. My blower has quit working. It was intermittent and now nothing at all. Can anyone tell me the location of the blower motor? Is this something that you think I could fix myself?

Inside up above the passenger footwell. See: A/C fan quit (A/C seems to work) - Pontiac Solstice Forum

Help!

Can anyone show/tell me where the cover is that needs to be removed to access the resistor? The guy on the solstice forum took his pictures down. So far, I rolled back the carpet, took the plastic velcroed panel off, removed the fuses so I don't kill myself, but for the life of me I can't find the cover that needs to be removed to get to the heater blower. etc. From what I read, it should be pretty simple.

I don't have a Sky, but I assume you'll have to remove #37 here (above the fuse box and behind the glove compartment):



Then you should be able to reach up to the resistor pack (#12 here):

UPDATE: You may need to remove the glove compartment itself. Found this as well (Solstice again): A/C fan quit (A/C seems to work) - Pontiac Solstice Forum

I did it! I did it! I pulled out the resistor and sure enough, it was burned on the right hand plug just like everyone else. I'm ordering the new one right now. I left the harness in place because I felt if I took it off right now, I might forget how to put it back on by the time the new one gets here. I might need your help again once they get here. THANK YOU, THANK YOU, THANK YOU!

Funny, when I was researching the forum, I ran across my thread I wrote when the heat first went out. That was in 2011! I've been without heat and air for two winters and two summers since then. Over something this simple.

Me again guys. Things got pretty hectic in the ole Pike house recently and I wasn't able to put the parts on until Sunday night. Works like a charm! Once again I can't tell you how much this forum has helped me. That being said, I have another question...

The blower is working fine however, Monday morning when I started the car, it had a little drag like the battery was low. At lunchtime start, it had two drags, ruuugh, ruugh and then started. By time to go home, I got three turnovers and then click, click, click and it wouldn't take a jump. I was wondering if there was anything possible I could have done to cause a drain on the battery? All I did was plug everything back in but I did need to pull on the wires a little. What do you think?

Could easily be coincidence. How old is your battery? We've seen that when they die they seem to go suddenly.
