Symptom:

Most of the time, when I start my '88 TE, all is well with my climate control unit. Specifically, when I push the top most fan speed button, it really blows a lot of air around. Lately, when I start the car and do the same as above, sometimes nothing happens. Pushing any of the other AC buttons on the left, even the max defrost, makes no difference. Further, I have found that when I get no response from the fan speed button and the rest of the climate control unit, I can restart the car and all is back to normal.

Question: Is it time to R/R the Climate Control unit?

Many Thanx.
