97 E 420 AC issues

Hey guys hope all are well was hoping to get some insight on my ac issues with my 97 E 420 with 45000 original miles on it- I have been reading the stickies about AC issues so I decided to run the diagnostics and then post and see what you guys thought prior to going to the Indy-
Heres what I found on the codes
Got a 1227- outside temp indicator
1235- Series Interface K1 connection to Instrument cluster-
cleared these codes they never came back

I ran the other diagnostics and got this: all converted to fahreinheit
1- 84.2
2-80.6
3-87.8
4-87.8
5- 86
6-143.6
7-00
8-80.6
outside temperature is 84-- My compressor is not engaging and my EC light is not in the stuck "ON" position - Any help or thoughts would be greatly appreciate- Thanks Cole

Before you fall for commercial spamming - you can buy a can of R134 with dye and dye only at any automotive story and add it to the system, checking pressure #7 for couple of days to see how the system holds.
