Yes..here they are

Almost all 94 I have seen all use the fused sperated relays..the 93 had a fused high fan , but not on the low. My 124 chassis shows 93/94 as that production change, but not ness. on the 202.
But, SB.... I believe you to be correct on the primary/sensor side of the fan circuit b/c the parts does not show a pigtail pressure sw for 202 like they do for 124. They show the variable sensor you mention and that would control all funtion inputs..[ meaning pigtail is no longer used on that chassis]

So, the secondary/load side uses the fused relays and R15 dropping resistor just as the 124 of 94/95 , but I do not think the sensor is pigtail pressure, as you mentioned . [ but only on the 202/C class]
Does your schematic show that sw. ?? [ i do not have a 202 schematic]
A note to the poster..if you find the original 15A fuse on top of the low fan relay to be the cause of your complaint, [ which is common], be aware that Benz has allowed a change to 25A on that circuit..evidently they had found the 15A to be slightly under-rated for low fan. You may want to try a 20A first. High is still the 30A.
