I started at the blower motor, and ended at the a/c control switch on the dash power stops there. can someon please inform me as to where the Relay is located for this part of the systom. All fuses and relays on the relay panel are good. but thats not where the relay is located.

If you have ECC, the '93 940 diagram shows a "dual relay" (my term for item 2/10) called a "Power unit ECC", which appears to control item 6/28, the "Cabin fan motor".

The pictorial shows 2/10 to be near the fan motor.

It has 2 harness plugs and appears to be fastened in place by 4 flange bolts, 2 on each side.

Fan ground side comes in on a blue/black wire at terminal 1A,
and connects to grounds via white/black wire from terminal 2A,
when a coil is grounded via blue/red wire from terminal 3 to Control module pin 22.

'93 940-NA (current) — 240s (one V8) — 140s — 122s — since '63.

For MCC 940 B230F/Tcars, you have no relay unlike earlier versions which have relays behind the glove box. Ditto for ECC-equipped cars. For B234F engine cars, you've got a cutout relay for A/C behind the right front headlight.
