Thomas 153 hydraulic control issues

[Mattman17]

Hi everyone I'm new to this site I bought myself a 2003 Thomas 153 this summer just for person use. I picked up a new plow for it. I never had to use my wet lines yet until now. I installed the plow and tried the hand control and I have no response at all from my finger switch on the left hand side. When I turn on the aux on top it will send the plow to one side hard and stay there. If I switch the lines over then the plow will go hard the other way but I cannot turn the plow. Any feed back on what I could look for I would really appreciate it. Thanks in advance.

Auxiliary hydraulics (solenoid operated - standard) A switch located on the L.H. steering control lever is used to engage the loader's auxiliary hydraulic circuit to power attachments such as post hole augers, sweepers, etc. Pressing and holding the switch in position left provides hydraulic flow to the female quick connect coupling located at the front of the lift arms . Releasing the switch returns the auxiliary hydraulic circuit to neutral, stopping the hydraulic flow. Pressing and holding the switch in position right (fig. 2.8A) provides hydraulic flow to the male quick connect coupling located at the front of the lift arms releasing the switch returns the auxiliary hydraulic circuit to neutral, stopping hydraulic flow. For continuous flow to the auxiliary hydraulic circuit, a toggle switch is located on the L.H. instrument panel Placing the switch in the "ON" position provides continuous hydraulic flow to the female quick connect coupling located at the front of the lift arms . To stop hydraulic flow to the auxiliary hydraulic circuit, return the switch to the "OFF" position . When the switch on the instrument panel is in the "ON" position, the switch located in the L.H. control lever is not operable. Judging by the writing of you, you have a problem with left halde finger switch or wiring to/from it. There are available online service manul,owner manual and parts manual.
