bought new motor and regulator for mercedes , not good when your on first name basses with parts guy lol , he will take back what i dont need nice of him , now i have to look up how blower comes out!

It is not too hard, actually pretty intuitive once you remove the panel over the passenger footwell. The entire job from start to finish should take about 1 hour.

it was blower that was sticking, re&re blower 1/2hr start to finish thank god i had the 2 torx bits ,wife was dissapointed that I was back bugging her so soon , now to fiquire out still aux fan trouble

After recharging the A/C on the '87 300d, the aux fan now comes on whenever the compressor runs. The "book" says that the pressure has to build to about 300 psi or the coolant temp over 105C to turn on the aux fan. Yet the high side pressure was about 240 psi when charging and the coolant temp was no where near 105C. One possibility is that my gauges didn't catch a spike when the comp. turned on or that the pressure transducer may be switching at a lower pressure. But this may be a good thing considering the head cracking issue. I have been trying to figure out a way to run the aux fan at a lower temp than 105C and this may work.

300 PSI sounds too high for the first activation of the auxiliary fan, but I am not familiar with the switch used on your car.

On the 210, the auxiliary fan starts up at 14 bar, or just over 200 PSI and continues to run until the pressure drops below 11 bar, or about 165 PSI.
