Intermittent Air conditioning (and heat) blower

'88 300SEL

Previous owner replaced the...

Climate control switches (Temp wheel/buttons/Fan control)

...and problem still exists:

Today in 90-degree heat and blower on low, auto, or high and temp wheel completely in blue A/C turned itself off. Then turned back on. Then again and again sometimes with a low fan and sometimes slightly higher. Sunroof closed. Windows closed. When air blows it "usually" blows cold (I'll continue to track this)

I believe the car also did this in the winter with the heat cycling on and off. For this I purchased an INTERIOR TEMPERATURE SENSOR HEAT EXCHANGER at heater case but have not installed it as of yet.

For the A/C do you think I need...



AMBIENT AIR TEMPERATURE SENSOR on the front inner roof rail

If so can you point out the specific location of the installations?

Thank you
