Replying to: mswhiz (Aug 02, 2008 11:42 am) Cool, thanks for responding. Hopefully that will fix it for you, if it does, I will give it a try too.   Update:   We have checked every fuse again that we could find and it is definetley not one of the fuses we can see. If it is not what you said, then I am getting scared it is the wiring which means I might have to take it to a shop.   The actual AC is now turning on and off on its own sometimes when I am driving as well which does seem like it might mean a short.   It also no longer stays on every time we turn it off, it not only does it about half the time.   Also, although doors/hood shutting never affected it before, it is now sometimes turning it off (when the car is already off and no key in ignition).   Oh and I found a better way to turn the thing off. Instead of unplugging the battery, I can unplug the main AC wire. It is much faster and easier to do. Wahoo!!! My boyfriend has the blazer right now, but when he gets home I will have him try turning it off and waiting for a minute or 2 and then restarting it.   -------------------------------------------   I will wait till I hear back from you before I do anything else and hope it is what you said. If it is, then it is something I can do myself or can get someone to do for me which will save me a lot of money.

Update:   Sorry, it has taken so long to get back. Well here is the answer you have been waiting on.   My blower fan has stopped staying on after I turn the car off. So it must of been the ignition switch.   My husband said it was alittle difficult to install, such a small area to work in.   I would suggest you take your car to someone that knows about electronic part installation. Good luck. I hope it helps. Replies to this message: desia (Aug 12, 2008 1:02 am)

#6 of 6 My AC Stays On/Even when heat is On. by fford34 Feb 26, 2009 (6:05 pm)
I have a 2000 Chev Blazer which I just Bought. When I turn the heat on and the blower it seems to work fine. But as soon as I start driving the blower sounds like it gets blocked and stops blowing strong. I cheched under the hood and found that the air conditioning was on and that the hose and dryer were completely ice up.The controls were set for heat.Has any one encounterred this problem and if so can you help me find a solution. Thanks
