Question 1991 300e A/C question

My 1991 300E (3.0) has this A/C problem. The condensor engages. The freon has been checked and is sufficient. The high and low side pressure is ideal. My aux fans do not go on when the a/c is turned on, so I do probably need a new temp sensor for the aux fan.

When I bypassed the sensor and got the aux fans to work, there was still no cold air at all! What part or parts should I be replacing???

I want do make this repair myself and just need to be pointed in the right direction. Thanks in advance for any direction anyone can provide. This site is great!!
