Hey everyone! I’ve been getting a 1985 jaguar xj6 VDP back on the road and recently put a motor in from another jaguar after mine quit. After getting it back on the road I found out that the blowers would not turn on. When I give the green/white wire on the relay box power the fans blow. I have replaced the relay box, the two fuses in fuse box, and the in-line fuses in the passenger foot well. Before the engine swap the low speed setting never worked and the servos did move from cold to hot while driving every few minutes. After replacing all of the vacuum lines and routing them the correct way they don’t move when the switch is moved. Any help would be appreciated!

 

After I apply power either wire the blowers turn on and after I stop they run for about about ten seconds and shut off. The servos are not moving with either switch so they aren’t working either.
