Air conditioner gave up a couple of months ago, have had to take care of other problems first, now I need some help with this one. Blower blows hot air in all settings, even on vent without the A/C running. I've checked the mono valve, rubber seals look good. I don't know if this is related, but I'm also experiencing some vacuum leaks, however they started well after the A/C gave out. Vacuum leak symptoms are intermittent and are as follows: engine runs on for several seconds after ignition is turned off; door locks do not activate. Again, the vacuum problems do not occur every time I shut down the engine or lock the doors (BTW - door locks always work when engine is running), and they did not start until well after the blower started blowing hot air, so I don't think the vacuum problems are causing the hot air.
