A/C system surge?

[GoofyGuy]

Well I didnt know what to call it but I will still expain to see if you guys have similar problems? If you have been keeping track this is problem 4 with my R/T. If the A/C is on in any setting when its on a/c setting on it will blow cold quick but theres still and issue. It will got Hot for a second or two every few minutes. With a digital thermo in hand a friend and I went on a ride and sure enough its 66 at the vent then jumps to 89 for 3 seconds at a time. Its random in time. Anyone else?

Does the temp go directly from 66 to 89 or does it slowly climb to 89 and hang there for a few seconds and then slowly climb back down??? Also do you have climate control?

no I dont have climate control. it jumps real fast then back down. It takes maybe 3 seconds to jump to 89 and that could be the refresh of my thermo. And it goes back to super cold instantly.

For it to make that quick of a change there would have to be a temperature blend door opening and closing suddenly for no reason, the ac just turning on and off would not be able to change temps so rapidly.

on a ride today I can hear and feel the a/c comp turning on and off for some reason. I wonder if the swich is going to high heat for a breif moment for some reason. This will be the last straw on my back. Any little thing and the dealer can have it back.
