Not sure if this is the right section, but here goes...

I don't use my A/C much except for defrost. The other day I had turned it on and it worked fine, then I turned it off for a few minutes and then back on again. Within a minute or two it was blowing VERY hot air, so I shut it off. A day later I turned it on and it blew cold air for about a minute and then got hot again.

So here is what has been done/checked...
- The compressor is working, it kicks on when the A/C is turned on.
- The freon is charged, had it checked at the shop, good pressure and all.
- The resivoir and A/C lines under the hood are getting cold, telling me that everything there is working properly.

Is there a servo/switch or something in the dash that could be causing this? Does Autotap have any climate control options that I can check? Anyone with ANY idea's? TIA.

 

Sounds like you could have a vacuum leak in your control tubing. This would allow the damper to swing and push the air through your heating coil.

 

Is there an easy way to check this? Or fix it for that matter? TIA.

 

Anyone???
